Avoiding a hangover starts with alcohol choices

undefined

Scientists say it takes 5-7 drinks for men to feel the effects of drinking too much and 3-4 for women. The two main triggers are alcohol and sugar.

The study in the Annals of Internal Medicine says to choose drinks with lower alcohol content and avoid sugary mixers.

Stick with clear alcohol like vodka and gin because they don't contain a byproduct that increases the severity of a hangover.

If you're a red wine drinker, aim for dryer reds with lower alcohol content.

And always eat something so you don't drink on an empty stomach.
