How rough will tomorrow morning be? This (totally non-medical) calculator weighs the drinks you knocked back, the water you did NOT drink, your hours of sleep and what was in your stomach to forecast the incoming hangover. Spoiler: water always helps.
A (barely scientific) estimate of how rough tomorrow morning will be, weighing drinks, water, sleep and food.
A hangover is no mystery: it comes down mostly to how much pure alcohol you took in (those famous alcohol units), how dehydrated you are and how much you slept. There's also a detail few people know: congeners, the compounds formed during fermentation that give a drink its aroma and colour. Dark spirits like whisky, rum and red wine carry far more of them than clear vodka or gin, which is one reason the same amount of alcohol can leave you with a very different head.
The most useful thing to remember is simple: a hangover begins while you drink, not the next morning. Alternating each drink with a glass of water, eating something and stopping earlier genuinely move the needle; and if you're getting behind the wheel, the only threshold that counts is the legal one, not how you feel. The same care lives behind the bar, where whoever is serving counts alcohol units and watches the blood-alcohol limits for anyone driving. If you want the serious numbers, try the blood alcohol calculator below — and if you truly feel ill, see a doctor.

Absolutely not, it's a game. For the serious numbers use the blood alcohol calculator below, and if you actually feel unwell, call a doctor.
An entertainment game, not medical advice. Drink responsibly and stay hydrated.
