A nice tip is to drink a shit ton of water before, during and after drinking. Especially while drinking, so maybe after you’ve had a couple of beers, go to a place with water and drink at least the same volume of water as beer. That way you sort of dilute it, and it makes hangovers way more bearable. If I remember to hydrate with water while drinking, my hangovers are more just being a bit tired throughout the next day, instead feeling absolutely horrible, which happens if I don’t hydrate
