Pure alcohol, and a guide to how long it takes to clear

Rough time to break down
- This is an average-case estimate. How fast alcohol breaks down varies widely with your body, food, and the day, and in reality it often takes much longer than this.
- Never use it to decide whether the alcohol has cleared or whether you can drive. Drink-driving is prohibited by law regardless of how much time has passed.
- It is not a basis for any medical or legal decision.
Why there is no single number →
This is as far as a calculator goes.
It's one number for an average person, and the real you shifts with your body and the day. The Nomicho app gives you:
- The rise and fall in real time, as a live curve rather than a single number.
- Estimates tuned to you: height, flush response, and how often you drink, not just sex and weight.
- A safe-side band instead of false precision.
- A hangover forecast, a look at the next day, and the patterns across your own sessions.
