Addiction and Anxiety: The Vicious Cycle

By Gary Clinton·Addiction specialist·Author of Never Give Up·Updated June 2026 · 7 min read

Few things in addiction are as cruel as the relationship between substances and anxiety. The very thing you reach for to calm down is, a few hours later, the thing winding you up. You drink to take the edge off, and wake at four in the morning with your heart pounding and a sense of dread you cannot explain. If that is your life right now, I want you to know two things: it is not in your imagination, and you are not going mad. There is a clean, understandable mechanism behind it — and once you see it, you can start to break it.

I spent years in this loop myself. I used to manage my anxiety with drink and drugs and genuinely believed they were the only things holding me together. What I could not see at the time was that they were the engine driving the anxiety up, not the brake slowing it down. Let me explain how substances both soothe and worsen anxiety, what hangxiety actually is, the chicken-and-egg of which comes first, and how the loop finally gets broken.

How a substance soothes anxiety — at first

Anxiety lives in the body as much as the mind: a tight chest, a racing heart, a head that will not stop scanning for danger. Alcohol and many drugs press down on that overactive nervous system. They are, in the short term, genuinely calming. The worry loosens, the body softens, and you finally feel like you can breathe. Your brain takes careful note: when I feel anxious, this fixes it. That is the seductive part, and it is why so many anxious people end up self-medicating without ever deciding to. I cover that pattern in detail on my page about self-medicating to cope.

How the same substance makes anxiety worse

Here is where the trap snaps shut. Your nervous system is built to find balance. When a substance forces it down into calm, the body fights back to restore the level — and when the substance leaves your system, that counter-push overshoots. You do not just return to baseline; you bounce above it. The result is rebound anxiety: more dread, more agitation, more racing thoughts than you started with.

With alcohol, this has an everyday name: hangxiety. That grim, wired, doom-laden feeling the morning after is not just guilt about what you said or did. It is your nervous system rebounding from the sedation, your stress hormones running high, and often dehydration and broken sleep piled on top. You feel anxious because your body is, chemically, in an anxious state. And the cruel logic of it is obvious: the one thing that has always reliably quietened that feeling is another drink.

Hangxiety is not weakness or imagination. It is your nervous system overshooting as the alcohol leaves — rebounding into the very feeling you drank to escape. The cure for it looks exactly like the cause.

The vicious cycle, step by step

Put those two halves together and you get a self-feeding loop:

  1. You feel anxious, so you use to settle it.
  2. It works — for a few hours you feel calm and relieved.
  3. As it wears off, your nervous system rebounds and anxiety climbs higher than before.
  4. Now you are more anxious than when you started, with hangxiety or a comedown on top.
  5. The most obvious relief is the thing that caused it — so you reach for it again.

Each lap makes both problems bigger. The anxiety deepens because it never gets treated, only postponed. The using escalates because you need it more often, and for less return. This is one of the surest ways a coping habit hardens into a dependency, and it is exhausting to live inside.

Which comes first?

People often ask me whether the anxiety caused the addiction or the addiction caused the anxiety. The honest answer is: it goes both ways, and it does not much matter which came first — because by the time someone reaches me, the two are tangled together and feeding each other.

Sometimes anxiety came first. Someone lived with an anxious mind for years and found that drink or drugs were the only thing that turned the volume down, and a dependency grew from there. Sometimes it is the other way: the substance use came first, and heavy, regular use rewired the nervous system into a chronically anxious state it never had before. Often it is both at once, in a knot. The useful thing is not to win the argument about origins. It is to recognise that both halves are now real and both halves need treating.

Breaking the loop

The good news — and it is genuinely good news — is that this loop, precisely because it is a loop, can be broken at more than one point. You do not have to fix everything at once.

One important note: I am a CBT-qualified therapist, not a doctor, and this page is not a substitute for medical or psychiatric care. If you think you have an anxiety disorder underneath your using, please get it properly assessed. When anxiety and addiction travel together, treating them together is what actually works — and you deserve that, not a half-measure.

Frequently asked questions

What is hangxiety?

Hangxiety is the spike of anxiety, dread and agitation many people feel the morning after drinking. It happens because your nervous system rebounds as the alcohol leaves, your stress hormones run high, and poor sleep and dehydration add to it. The feeling is chemical, not just guilt.

Does anxiety cause addiction, or does addiction cause anxiety?

Both, and they feed each other. Sometimes anxiety came first and the substance was used to cope; sometimes heavy use rewired the nervous system into a more anxious state. By the time it's a problem, the two are usually tangled — so both need treating together.

Will my anxiety get better if I stop using?

Usually yes, but often not straight away. Anxiety can spike for a while as your nervous system recalibrates, then settle. If there's a genuine anxiety disorder underneath, that needs treating in its own right too — ideally with proper support — rather than waiting for it to lift on its own.
