Alcohol and Depression: Why Each Makes the Other Worse and How to Break the Cycle

Why Alcohol Helps at First and Then Makes Things Worse

The first sips of alcohol boost the action of the inhibitory neurotransmitter GABA and trigger a release of dopamine, so a person feels relaxed, less anxious and in a better mood. This relief is real, but short-lived. As soon as blood alcohol levels start to fall, the brain compensates for the inhibition with a rebound reaction: arousal, anxiety and irritability increase, and sleep is disrupted. That is why an evening of drinking “to unwind” often ends with waking up early with heavy, dark thoughts.

With regular drinking, the nervous system adapts. Receptors become less sensitive, the serotonin and dopamine systems are depleted, and stress hormone levels rise. Pleasure from ordinary things fades (this is called anhedonia), and without alcohol a person feels low and inwardly tense. They start drinking not for the pleasant effect but simply to get back to feeling “normal” — and this is one of the key mechanisms by which addiction develops.

Hangover Anxiety and Depression

The morning after drinking, many people experience not only physical discomfort but also marked anxiety, guilt, shame and hopelessness. This is a sign of mild withdrawal combined with the effects of disrupted sleep. In people prone to depression, these episodes can grow longer and more severe and gradually merge into a constant background of low mood.

Why People Need to Drink More and More

Over time, more alcohol is needed to get the same effect — this is tolerance. The more a person drinks, the stronger the next-day “crash” and the deeper the drop in mood. In this way, alcohol turns from a way of coping with feeling bad into the main source of feeling bad.

Which Comes First: Depression or Alcohol?

Doctors distinguish two main scenarios. The first is alcohol-induced depression (in ICD-10 it is classified among mental and behavioral disorders due to alcohol use; in DSM-5 it is called substance-induced depressive disorder). It develops during regular drinking or withdrawal and usually eases noticeably within a few weeks of sobriety. The second scenario is independent depression, which existed before the heavy drinking began or persists a month or more after a person stops drinking.

In practice, the line is hard to draw: a person may have started drinking to cope with long-standing low mood, and then alcohol made it worse. That is why the doctor asks in detail which symptoms were present before regular drinking began, whether there have been periods of sobriety and how mood changed during them, and whether relatives have had depression. A final conclusion is often reached only after 2–4 weeks of abstinence, once the acute effects of alcohol have worn off.

Signs of Alcohol-Induced Depression

Low mood appeared after regular drinking began, gets worse in the days after drinking and during withdrawal, and comes with anxiety, insomnia and irritability. After a few weeks of sobriety, mood gradually evens out, and sleep and interest in everyday activities return.

Signs of Independent Depression

Low mood, loss of interest and lack of energy were present before the heavy drinking, recurred during alcohol-free periods, and close relatives have had episodes of depression. After stopping drinking, the symptoms last longer than a month and require separate treatment by a psychiatrist.

Signs That the Cycle Has Already Taken Hold

The vicious cycle forms gradually, and the person often doesn’t notice it. They explain their drinking by fatigue, work stress or insomnia, and blame feeling unwell on outside circumstances. Loved ones see something else: drinking becomes more frequent, mood between drinking episodes gets worse, and attempts to talk about it are met with irritation. Below are signs that it’s worth seeing a specialist, even if the drinking seems moderate.

• You drink to fall asleep, calm down or “stop thinking,” not for the company or the taste
• Your mood the day after drinking is noticeably worse than it was before
• Without alcohol you feel sadness, anxiety, irritability or emptiness
• Your interest in work, hobbies and loved ones has been fading for weeks
• Your sleep is disrupted: it’s hard to fall asleep without alcohol, and you wake early with heavy thoughts
• You have thoughts that life is meaningless, feelings of guilt and of being useless
• You can’t cut down on how much you drink, even though you want to
• People close to you say you’ve changed and become withdrawn or short-tempered

Why the Combination of Alcohol and Depression Is Dangerous

The main danger is an increased risk of suicide. Depression in itself comes with a sense of hopelessness, while intoxication lowers self-control and increases impulsivity. So thoughts that a sober person can keep in check become especially dangerous when they are drunk or badly hungover. If you notice such thoughts in yourself or someone close to you, that is a reason to seek help right away — not once “things settle down.”

In addition, alcohol gets in the way of treating depression. Many antidepressants work less well with regular drinking, and some sedatives and sleeping pills combined with alcohol can suppress breathing and consciousness. Adherence to treatment drops: the person misses appointments or abandons therapy. Sleep, work, relationships and finances suffer — and every new problem becomes another reason for low mood and another drink.

Effects on the Brain and Body

Long-term heavy drinking disrupts the frontal lobes of the brain, which are responsible for planning and emotional control, and depletes B vitamins. This can show up as poorer memory and concentration and as apathy, which looks like depression from the outside and makes it worse.

Effects on the Family

Loved ones live under constant strain, try to control the drinking, and feel guilty and powerless. They often develop anxiety and depression themselves, so helping the family is an essential part of treatment, not an optional extra. It’s helpful for relatives to see a specialist even before the person themselves agrees to treatment.

How Depression Is Treated Alongside Alcohol Addiction

Current clinical guidelines agree on one point: addiction and depression should be treated at the same time, not one after the other. Waiting until a person “quits drinking first” without supporting their mood is dangerous — sadness and anxiety during withdrawal often lead to relapse. Treating only the depression without addressing the drinking is also pointless. That is why the best results come from an addiction doctor (narcologist), a psychiatrist and a psychotherapist working together under a single plan.

The first stage is stopping drinking safely. After long binges and with severe dependence, withdrawal can be serious, so it is carried out under a doctor’s supervision — at home or in an inpatient unit. Then, once the person is stable, the psychiatrist assesses the depression and, if needed, prescribes antidepressants from classes that are compatible with addiction treatment, while the addiction doctor selects medications to reduce cravings. Psychotherapy starts in parallel.

Psychotherapy

The best-studied approaches are cognitive behavioral therapy, motivational interviewing and relapse prevention programs. They help people recognize triggers, cope with cravings and negative thoughts, build new ways of relieving tension, and regain an interest in life.

Medication Support

Medications are chosen only by a doctor after an examination, taking into account the severity of the depression, liver function, other conditions and other medicines. Taking antidepressants or sleeping pills on your own while drinking is dangerous. It’s important to tell your doctor about everything you take, including over-the-counter products.

Support After the Main Course of Treatment

Regular sessions with a psychotherapist, mutual support groups, attention to sleep and daily routine, and work with the family reduce the risk of relapse of both depression and drinking. It’s important to agree with your doctor in advance on what to do at the first signs of worsening mood or stronger cravings, so you don’t have to face them alone.

What to Do If You Recognize Yourself or a Loved One

The first step is to honestly acknowledge the link between drinking and mood without blaming yourself. Depression and addiction are medical conditions, not a weakness of character. It helps to keep a diary for a week, writing down how much and when you drank, how you slept and what your mood was like: such a diary clearly shows that the hard days follow drinking, and it will be useful to the doctor at your consultation.

Don’t try to quit abruptly on your own after a long binge: it can be dangerous. It’s better to see an addiction doctor, who will assess the risks and suggest a safe way to stop. If the drinking isn’t daily, you can start with a consultation with a psychiatrist or psychotherapist, including online. For loved ones, it’s important to talk about their feelings and concern rather than interrogate or issue ultimatums, and to offer concrete help — for example, booking an appointment together.
