Why Can't I Stop Drinking?

You tell yourself you're going to stop.

Maybe you make it through Monday. Then Tuesday. You feel good about yourself. But by Wednesday, something happens. You've had a stressful day, you're feeling anxious, bored, lonely or angry. You have a drink.

And then another.

Before long, you're back where you started.

So why can't you just stop?

The simple answer is that, for some people, drinking is no longer just about wanting a drink. The brain has learned that alcohol does something for you.

And that can make stopping much harder than simply making a decision.

Alcohol changes the way the brain learns

Alcohol affects the brain's reward system. When you drink, dopamine and other brain chemicals are involved in creating feelings of reward and reinforcing the behaviour.

Your brain starts making connections between alcohol and the things around it.

Friday night. A particular pub. Finishing work. An argument. Being alone. Seeing a bottle in the cupboard.

These things can become cues that tell your brain: this is when we drink.

Over time, drinking can become less of a conscious decision and more of a learned pattern. The brain's habit and reward systems become increasingly involved, while the parts of the brain responsible for decision-making and impulse control can become less effective, particularly during stress or strong cravings.

This is one reason someone can genuinely want to stop drinking and still find themselves drinking.

It isn't necessarily a lack of willpower.

Sometimes you aren't drinking to feel good

This is an important part of addiction.

In the beginning, you might drink because it feels good. You relax. You become more sociable. You stop thinking so much.

But over time, the reason you drink can change.

You might drink because you don't want to feel bad.

Alcohol can temporarily reduce feelings such as anxiety, stress and emotional pain. But with repeated heavy drinking, the brain's reward and stress systems can adapt. When the alcohol wears off, negative feelings can become stronger, creating a powerful reason to drink again.

So the question can change from: “Do I want a drink?” to: “How am I going to get through tonight without one?”

That's a very different problem.

What is the drinking doing for you?

This is where it can be useful to look beyond the alcohol itself.

Sometimes drinking becomes a way of meeting a need that isn't being met elsewhere.

Maybe you need relief from stress, pressure or responsibility; connection because you feel lonely or disconnected; confidence because social situations make you uncomfortable; escape because your thoughts don't switch off; rest because you're exhausted and never seem to get any time for yourself; comfort because something hurts emotionally; control because so much else in your life feels out of control; or sleep because you struggle to switch your mind off.

This doesn't mean there is always one hidden reason behind someone's drinking. Addiction is complicated, and people's experiences are different.

But asking “What does alcohol do for me?” can sometimes be more useful than simply asking “Why can't I stop?”

Because if alcohol is helping you cope with something, taking alcohol away without addressing that something can leave a very uncomfortable gap.

The brain can get stuck in a cycle

A useful way of understanding alcohol addiction is as a cycle.

You drink. You get relief or reward. Your brain learns from the experience. You encounter a trigger. You experience a craving. You drink again.

Over time, the cycle can become increasingly automatic.

And if dependence has developed, stopping can also produce physical or emotional withdrawal symptoms, which can make drinking feel like the quickest way to feel normal again.

This is why some people eventually find themselves drinking not because they particularly enjoy it, but because not drinking feels worse.

That doesn't mean you're broken.

It means your brain has adapted to repeated alcohol exposure. And importantly, the brain is capable of change too. Neuroscience research shows that brain plasticity is involved not only in the development of addiction, but also in recovery.

So, how do you actually stop?

There isn't one answer.

For some people, changing their drinking habits may be enough. For others, particularly where dependence has developed, stopping suddenly can be dangerous and medical advice may be needed.

Therapy can also help you understand what sits underneath the drinking, recognise triggers, develop different ways of coping and begin changing the patterns that keep the cycle going.

The aim isn't simply to take alcohol away.

It's to understand why alcohol became so important in the first place and find healthier ways of meeting those needs.

You don't have to wait until your drinking has completely taken over your life before you ask for help.

And you don't have to prove that you're “bad enough” to deserve it.

Sometimes the most important question isn't: “Can I stop drinking?” It's: “What would I need in my life to make stopping possible?”
