Is it normal to argue when drunk?
Depends.It depends
Alcohol can make you less inhibited and more reactive, so arguments may happen more easily when you’re drunk. It’s common enough, but if it keeps happening or hurts people, it’s worth taking seriously.
Alcohol can lower your inhibitions and make it harder to read the room or manage frustration. Some people get louder or more argumentative when they drink; others get quieter, and plenty don’t change much at all.
An occasional squabble isn’t unusual, but repeated arguments—especially ones you regret or that scare or hurt someone—are a sign to rethink how much you’re drinking or what situations you drink in. You don’t have to wait for things to get dramatic to set a limit or take a break.
