Everything you've been told about alcohol? Wrong.

My doctor said one glass a day is good for my health.

There is no safe amount of alcohol.

In January 2023, the World Health Organization said it plainly: "there is no safe amount that does not affect health." Not a glass of red wine, not "just on weekends" — the risk starts from the first drop.

Here's why: when your body breaks down alcohol, it produces a chemical called acetaldehyde — a toxic substance that damages your DNA. Alcohol is classified as a Group 1 carcinogen, the same highest-risk category as tobacco and asbestos, and it's directly linked to at least seven types of cancer, including breast and bowel cancer.

The "a glass of wine is good for your heart" idea came from older, flawed studies — the science has moved on, even if the advice hasn't caught up yet.

Beer and wine are safer than spirits — it's the hard stuff that really does the damage.

Alcohol is alcohol, whatever it's poured from.

A standard beer, a standard glass of wine, and a standard shot of spirits all contain roughly the same amount of pure alcohol. Same ethanol, same effect on your body — the container just looks different.

The confusion happens because spirits pack that alcohol into a smaller volume, so it's easier to drink more of it faster without noticing. But what actually determines the harm isn't the drink type — it's how much you drink and how often. In real binge-drinking data, beer alone accounts for the majority of alcohol consumed during binges — the "safer" drink doesn't protect anyone in practice.

Black coffee or a cold shower will sober you up faster.

Nothing speeds up your liver. Nothing.

Your liver metabolises alcohol at a fixed rate — roughly one standard drink per hour — and nothing changes that. Not coffee, not a cold shower, not exercise, not a big meal beforehand.

Coffee makes you feel more alert, which is actually part of the danger: people who mix caffeine and alcohol report feeling less drunk than they actually are, with zero improvement in their real coordination, reaction time, or judgement. Feeling sober and being sober are two completely different things.

I've built up a tolerance, so it doesn't really harm me the way it used to.

Tolerance hides the damage. It doesn't stop it.

Tolerance means your brain has adapted to feeling less drunk at the same amount of alcohol — it says nothing about what's happening to your liver, your heart, or your brain underneath that. If anything, higher tolerance is linked to your body producing more of the toxic byproducts of alcohol breakdown, raising the risk of liver disease and cancer, not lowering it.

That's the trap: the better you get at "holding your drink," the harder it becomes to tell how much damage is actually accumulating, because the warning signs — feeling drunk — are exactly what tolerance switches off.

I keep having weirdly vivid drinking dreams since I quit — something's wrong with me.

It's not witchcraft. It's your brain healing.

Alcohol suppresses REM sleep — the stage where most dreaming happens. When you stop drinking, your brain does something called REM rebound: it starts making up for all the REM sleep it missed, all at once. That's why the dreams feel so intense, so specific, sometimes so strange.

It's not a sign you're relapsing, and it's not your subconscious trying to trip you up. It's the opposite — it's proof your brain chemistry is actively recalibrating. For most people this settles down within one to two weeks; for longer or heavier drinking histories, it can take two to three.

If it's happening to you right now: it's temporary, it's normal, and it means the healing is already underway.
