E337: How Your Nervous System Adjusts to Life Without Alcohol

0:00We expect to feel better once we stop drinking, and then sometimes we're more anxious, irritable, unable to sleep, and just bothered by everything. You might feel restless when you try to relax or exhausted, but then unable to settle down. Your emotions may feel more intense without alcohol there to shut them off. It's easy to interpret this as evidence that quitting was the wrong choice. Now that you're not drinking, your body seems even more activated. Maybe alcohol was the only thing that calmed you down. But there's a difference between regulation and chemical relief. Regulation is your ability to respond to what's happening and eventually recover once the challenge has passed Chemical relief changes your experience quickly so you don't have to remain present with it And like we talked about in last week's episode, if you repeat that process enough Your brain and body begin expecting alcohol to be part of how stress ends When you remove it, your nervous system doesn't immediately turn to what it would look like if you never developed that pattern.

1:11Alcohol may be out of your body, but the adaptations that your brain made in response to regular drinking don't disappear at the same speed. You're adjusting biologically while you're also learning how to handle stress and emotions without your fastest source of relief. It's a lot.

1:33Thank you.

2:07And I do need to make an important distinction here. Alcohol withdrawal exists on a spectrum, and severe withdrawal can be dangerous. Seizures, hallucinations, severe confusion, and major changes in heart rate or blood pressure aren't signs that you need to become better at tolerating discomfort. They require medical treatment. So please talk to a medical professional if you're nervous or if you're experiencing any of those symptoms. And episode 231 is a deep dive into alcohol withdrawal if you want to learn more about it. Even after acute withdrawal has ended or if you didn't experience too bad of a withdrawal, you probably don't feel normal right away.

2:51Your sleep is disrupted, your stress response may still function differently, and ordinary emotions can feel way more intense. Different parts of the nervous system recover on different timelines, and that's what I want to talk about today. When we talk about the nervous system, it's easy to picture one switch that's either calm or anxious, regulated or dysregulated. But it's an entire communication network that includes your brain, spinal cord, and the nerves carrying information between your body and brain. It continually adjusts things like your heart rate, breathing, digestion, attention, and emotional responses.

3:30The autonomic nervous system manages many of the functions that you don't consciously control. The sympathetic branch helps mobilize you, while the parasympathetic branch supports rest and recovery And one isn't bad and the other is good, you need both of them A healthy nervous system isn't calm all the time It can respond when something requires energy and then settle back down when the demand has passed But alcohol interferes with that flexibility by changing nervous system activity directly In the short term, it slows certain kinds of activity in the brain. So you feel it as your muscles loosening up, your thoughts slowing down, and whatever was bothering you is less urgent.

4:17That can feel like regulation, but alcohol isn't teaching your nervous system how to move through stress. It's just turning it off temporarily. With regular drinking, the brain adapts to alcohol's repeated presence. it's always trying to maintain a balance so when alcohol repeatedly slows it down the brain will make changes to compensate this is part of why alcohol stops feeling as relaxing as it used to you probably need more to get the same effect and you may feel increasingly restless anxious or uncomfortable when you're not drinking that discomfort can seem like proof that alcohol helps your anxiety.

4:59You drink, you feel temporary relief, and it confirms the idea that alcohol calms you down. But some of what alcohol is relieving is the activation that regular alcohol use caused. When you stop drinking, alcohol's slowing effect disappears before all of those adaptations reverse. So for a while, your system leans too far in the other direction, and that shows up as restlessness, irritability, shakiness, sweating, poor sleep, or sensitivity to stimulation. The severity varies enormously based on drinking and withdrawal history, health, and just your individual biology. One of the first adjustments involves GABA and glutamate.

5:47So GABA is your brain's primary inhibitory neurotransmitter, which means it reduces the likelihood that neurons will fire, aka it slows down brain activity. And glutamate is the primary excitatory neurotransmitter, so it makes activity more likely because it speeds up brain activity. Alcohol enhances inhibitory signaling while interfering with excitatory signaling, so this contributes to sedation, slowed thinking, reduced inhibition, and impaired coordination that are all associated with drinking. When alcohol repeatedly pushes the system towards slowness, the brain adjusts so it can continue functioning in alcohol's presence, and those adjustments contribute to tolerance and can leave the brain more excitable when alcohol is removed.

6:39And that matters because you may be several days or weeks without alcohol and still feel anxious, exhausted, and unable to sleep. And it's easy to assume that nothing's improving because you don't feel better yet. But your brain may already be making adjustments in healing while your experience still feels uncomfortable. Other changes take longer, including those that involve the autonomic nervous system. So one way that researchers examine autonomic function is through heart rate variability or HRV. Your heart isn't supposed to beat at perfectly even intervals. The time between beats shifts as your body responds to breathing, movement, emotion, and your environment.

7:27HRV measures some of that variation. Higher HRV is often associated with greater parasympathetic influence and adaptability, but higher isn't always better. HRV varies with age, health, medication, sleep, and activity, and a number that you see on your watch can't tell you whether your nervous system is regulated. A 2015 study followed 15 people with alcohol addiction and 13 healthy controls. They measured their heart rate and HRV during non-REM sleep, first within a month of the participants last drink and then again between two to four months of their last drink. At the first assessment, the addiction group had a higher heart rate and lower cardiac vagal activity than the control group.

8:17And even while they were asleep, their hearts showed less of the parasympathetic modulation that is associated with rest and adaptation. After four months of abstinence, the group did show substantial recovery in both areas. And that doesn't mean that everyone's autonomic nervous system fully recovers in four months. This was a small study and everybody's different, but it does show that measurable recovery can occur within the first year. A 2023 study looked at 42 adults in the first year of alcohol addiction recovery who wore a heart monitor for four days and they tracked their alcohol use for the next 90 days.

9:02Higher HRV and lower heart rate were associated with a greater percentage of abstinent days during the follow-up and that doesn't mean that increasing your HRV prevents drinking and relapse. As the body becomes better able to shift between activation and recovery, which is what the autonomic nervous system helps us do. Uncomfortable states become easier to tolerate without needing to escape them. You may not notice that your nervous system is improving, but you may notice that your heart doesn't pound for as long after a stressful conversation or that you can sit down at night without feeling itchy and restless.

9:43Those are improvements even if this stuff is still happening. Sleep is another area where people expect immediate improvement. Alcohol disrupts sleep, so it seems logical that removing it should help. Sometimes it does, but sleep can be one of the slower and less predictable parts of the recovery process. Alcohol helps you fall asleep because it's sedating, and then as alcohol is metabolized, sleep becomes lighter and more fragmented. You may not remember waking up every time you did, but you can still wake up feeling really tired. When you stop drinking, you also remove the method that your brain associated with falling asleep and relaxing.

10:25Even if alcohol was damaging your sleep quality, it was probably the cue that ended the day. Without that chemical transition, you can be tired and restless at the same time. So you may struggle to fall asleep, wake up a lot, have vivid dreams or nightmares, or just wake up early and not be able to go back to sleep. Poor sleep can make you more reactive, less patient, and less able to concentrate. You might start thinking that sobriety isn't working or that you felt better when you were drinking. But alcohol may have helped you become unconscious without giving you actual restorative sleep. Drinking again because you can't sleep restarts that cycle and teaches your brain that alcohol is still required.

12:33Emotional regulation can be another very slow adjustment. People expect sobriety to make them emotionally stable and then they get discouraged when they feel anxious, angry, sad, or overwhelmed. Some of that happens because alcohol had been numbing emotions, narrowing your attention, or helping you stop caring temporarily. So without it, emotions feel more immediate, and your nervous system is still recovering, so you may just shoot up from 0 to 100 in your personal experience. Emotional regulation doesn't mean preventing yourself from becoming upset. It means that your response can change as the situation changes.

13:18You can feel angry without immediately acting on it, or anxious without treating the anxiety as proof of danger, and sad without needing to make the sadness go away. You can understand intellectually that an argument is over or a problem has been handled while your body still remains activated. So progress doesn't mean avoiding that activation. It means noticing it sooner, creating a pause, and recovering in two hours instead of two days. If you used to stay up all night replaying conversations in your head or figuring out what you wish you would have said and you don't do that anymore or you do it much less, that is huge progress.

14:02Your nervous system learns through experience. when you feel angry and you don't send the text or you feel anxious and you don't immediately cancel the social thing. Each time you learn that discomfort doesn't require an immediate reaction and that the emotion can rise and fall without alcohol. And you're also learning that emotions aren't instructions. Anger may show you that a boundary has been crossed but it doesn't decide how you communicate. Anxiety may alert you to uncertainty, but it doesn't automatically mean that you should avoid the situation. And guilt may tell you that your boundary or choice disappoints others, but it doesn't mean that you were wrong and that you should go back to people-pleasing.

14:50Alcohol gave you one response to many emotional states. Change the state quickly. Sobriety requires you to identify your actual problem and then choose a response that fits it. That takes time to learn. All of these processes happen on different timelines. The brain recovers a lot in the first year and continues to recover for years after we quit drinking. Some change can happen relatively quickly while others continue for months and that explains why recovery can feel inconsistent. Your energy could improve before your concentration or the other way around. Your sleep can improve while your emotions remain intense.

15:32You may feel stuck for weeks and then realize that you're following conversations more easily or that you're recovering from stress quicker. A difficult week also doesn't mean that you're going backwards. Sickness, poor sleep, stress, and major life changes place a lot of demand on our nervous system, and a system under greater demand has more activation even if it's functioning better. So how can you help your nervous system adjust? First, stop expecting yourself to feel calm all the time. If calm becomes your standard, every moment of anxiety or irritation feels like evidence that something's wrong.

16:11The goal is flexibility, responding to stress, and then recovering faster. Regulation also isn't always relaxation. If you're angry because someone repeatedly ignores a boundary, calming yourself without addressing that boundary doesn't solve your problem. If you're anxious because you've avoided an important task, taking action is going to help you more than trying to convince yourself to not be anxious. And if you're overwhelmed because you pressure yourself to be productive, you may just need a snack and to ask for help rather than a nervous system exercise or inspiration. In the beginning, you probably only recognize two states, I feel fine or I need a drink.

16:59Recovery develops more detail between them. You start noticing earlier signs and then those signs give you a chance to respond before you feel desperate for a drink. This adjustment happens through hundreds of ordinary experiences where you become uncomfortable, don't drink, and then feel different eventually. And predictability can help you too. Regular meals, a reasonably consistent sleep and wake-up time, movement, and periods with fewer demands can reduce preventable stress while your nervous system recalibrates. Connection matters too. So being with someone that's regulated themselves, hearing a familiar voice laughing or saying what's happening out loud can make an emotion easier to carry around.

17:47And being around people who are working towards the same goals as you and understand your experience makes this whole thing more normalized. Your nervous system adjusts to life without alcohol by repeatedly experiencing life without alcohol. It learns that you can finish the day, fall asleep, survive conflict, celebrate, and feel terrible without drinking. You're not going to teach it that alcohol is no longer required by never becoming upset, reminding yourself how bad alcohol is for your health, or by passively consuming resources. You'll teach it through all the times that you become activated, respond in a way that supports the life you want, and then discover that the feeling can change or pass on its own.

18:34If you want help practicing this, we work on this skill and more in the Living a Sober Power Life community. We talk about how activation shows up for you, how to recognize things sooner, and how to determine what you need instead of just drinking it away. You can learn more and join in the show notes. I would love to see you in the group. And remember, if you don't feel fully recovered yet, it doesn't mean that recovery isn't happening. Your nervous system spent years, maybe even decades, adapting to alcohol, and now it's adapting to life without it. It's going to take a little bit of time, and each sober day gives it another opportunity to learn that this is your new normal.

19:20So thank you for listening, and I will talk to you next week.

19:32Thank you.
