Eli5: does mixing alcohols really make you sick? If it does, why?

I’ve always heard things like liquor before beer. You’re in the clear and that mixing brown and white can go bad, but why are you not supposed to mix alcohols?

The saying around “beer before liquor” isn’t that mixing is inherently bad – it’s all about the order. That’s why the other half is “liquor before beer, you’re in the clear”. It’s also why the saying is more about liquor without mixers.

Alcohol doesn’t take effect right away. It takes time for the full effects to be felt. 30-60 minutes is typical, but some people can have longer or shorter times. As a result, if you stop drinking, you’ll still keep feeling drunker for a decent amount of time. Whatever you’ve drunk in the last half an hour takes a while to kick in. If whatever you had is a light beer, that’s fine. If it’s several shots of whiskey, you’re in trouble. You’re *going* to overshoot after a few drinks – doing the liquor first and beer second makes it more likely that you only overshoot by a single drink rather than a bunch of shots.

If your liquor has a bunch of mixer in it and the amount of time taken for one drink is similar to beer, that’s fine too.
