Anxiety after quitting alcohol: why it happens and how long it lasts

Feeling more anxious after you stop drinking is common. Why it happens, how long it usually lasts, what helps, and when to see a doctor.

Why stopping drinking can make you anxious

Alcohol is a depressant. It boosts GABA, the brain's main calming signal, which is why a drink can take the edge off. But the brain adapts. According to a review in the US National Institute on Alcohol Abuse and Alcoholism's journal, long-term alcohol dependence leaves the brain short of GABA overall, and withdrawal can make the brain systems involved in panic attacks overactive.

The UK charity Drinkaware describes the same thing in plainer terms. Alcohol suppresses the brain's "fight or flight" response. When someone drinks heavily for a long time, the nervous system gets used to that. When the alcohol level drops, you can go straight into fight or flight mode even though there is no danger. Drinkaware says every withdrawal symptom, from the shakes to anxiety, comes from that same response.

So the racing heart, the dread and the feeling that something is wrong are not a sign that you are falling apart. They are a nervous system that has not yet caught up with the fact that the alcohol is gone.

How long does anxiety last after quitting alcohol?

It depends mostly on how much and for how long you were drinking. Much of the research below looked at people in treatment for alcohol dependence, so it describes heavier drinking than many people who are simply cutting alcohol out.

The first few days. Withdrawal symptoms usually begin 6 to 24 hours after the last drink and often peak in the first 24 to 72 hours, according to Drinkaware. Anxiety, irritability and restlessness are on its list of typical symptoms. Drinkaware's summary: most people feel better within a week, and the first 48 hours are likely to be the worst.

The first weeks. For some people, symptoms last a week or longer, especially after heavy or long-term drinking, and psychological symptoms like anxiety can take longer to settle as the body and brain adjust. Researchers describe recently abstinent people reporting more anxiety and panic in the short term, and in some cases a fast heart rate and lingering anxiety for longer. In one study of 171 men in inpatient alcohol treatment, their day-to-day anxiety dropped quickly during treatment.

Months. In a study of 53 people treated in a residential program, 23 had an anxiety disorder at the start. Of those who were still off alcohol about 120 days later, 61% no longer had an anxiety disorder. Not all anxiety is withdrawal, though. Large surveys have found that in people with alcohol problems, anxiety disorders are often conditions of their own that need their own treatment.

This is also why doctors wait. Because withdrawal can mimic anxiety problems, a period of about four weeks without alcohol is needed before anxiety is diagnosed as a separate condition. The review adds that anxiety in early abstinence can lead people to think their anxiety is more permanent than it actually is.

So the honest answer: it is usually worst in the first few days, most people feel better within a week, and after long, heavy drinking it can take months to settle. If it is still strong after about a month, that is the point to talk to a doctor.

Why it matters: the drink that calms you down

Anxiety makes a drink very tempting, because alcohol really does calm you down for a while. A classic analysis of more than 300 relapses found that difficult emotions, conflict with others and social pressure to drink were involved in nearly three quarters of them. The problem is what comes after. Drinkaware notes that alcohol's calming effect wears off quickly, and that as it does, it can heighten feelings of anxiety, guilt and shame. That is the "hangxiety" many people know from the morning after.

Drinkaware also warns against drinking more to feel better, because your tolerance goes up, so you need more to relax, and that puts you at risk of dependence. Researchers describe a cycle in which anxiety and drinking keep each other going. A 2019 review found that drinking to cope with bad feelings is a strong marker of current and future problems with alcohol, and that up to half of people in treatment for alcohol problems also have an anxiety disorder, compared with about 11% of people in the US generally.

That is why the anxious first days are worth getting through without a drink. Every day you do, your nervous system gets a little more used to running without alcohol.

What actually helps

Slow breathing. The NHS recommends a calming breathing exercise for stress, anxiety and panic that takes a few minutes and works anywhere:

1. Sit, stand or lie down comfortably, with your feet roughly hip-width apart.
2. Let your breath flow as deep into your belly as is comfortable, without forcing it.
3. Breathe in through your nose, gently and regularly, counting from 1 to 5 if that helps.
4. Let the breath flow out through your mouth, counting from 1 to 5 again.
5. Keep going for at least 5 minutes.

It works best if you do it every day, not only when anxiety hits.

The basics that calm the nervous system. For the first days after stopping, Drinkaware suggests drinking plenty of non-alcoholic drinks while avoiding caffeine, eating regularly, finding ways to relax like reading, walking or music, and spending time with friends and family who support you. For anxiety in general, the NHS adds:

• talk about how you feel to someone you trust, or to a health professional
• exercise regularly, for example walking, running, swimming or yoga
• try to get enough sleep (if that is the hard part, read our guide to insomnia after quitting alcohol)
• cut down on coffee, tea, cola and energy drinks
• do not avoid the situations that make you anxious, but build up time in them slowly

Treatment, if it does not ease. Anxiety that stays can be treated. The NHS says the main treatments are talking therapies, usually cognitive behavioural therapy (CBT), and medicines, usually a type of antidepressant called an SSRI. In England you can refer yourself to NHS Talking Therapies without seeing a GP. Do not take someone else's tablets to calm down.

When to get help

If you drink heavily every day, speak to a doctor or a local alcohol service before you stop. Stopping suddenly when you are dependent on alcohol can be dangerous and even life-threatening, and they can help you stop safely.

Get medical help straight away if you have repeated vomiting, severe shaking, hallucinations, seizures or confusion after stopping.

See a doctor if your anxiety is still strong about a month after stopping, if it affects your daily life, or if you had anxiety before you started drinking heavily.

If you are in crisis or thinking about harming yourself, contact emergency services or a crisis line now.

Questions

Is it normal to feel more anxious after quitting drinking?

Yes. Anxiety is on the list of typical alcohol withdrawal symptoms, along with irritability, restlessness and trouble sleeping. It comes from the brain's fight or flight response kicking in as the alcohol leaves your system.

Can quitting alcohol cause panic attacks?

It can. Researchers describe recently abstinent people reporting more anxiety and panic in the short term, because withdrawal can make the brain systems involved in panic attacks overactive. The NHS breathing exercise above is designed for panic as well as stress.

Will one drink calm my anxiety?

For a short while. Then the effect wears off and the anxiety can come back stronger, and drinking to relax raises your tolerance. It is the one fix that keeps the problem going.

When does anxiety after quitting alcohol go away?

For most people it eases within about a week. After long, heavy drinking it can take months, but in studies of people who stayed off alcohol, it usually kept improving.
