This made me lol.
I definitely drink regularly and this does not prevent my hangovers, but not everyone is the same, because I get the WORST headaches/migraines. If I stand up my head just pounds and pounds...it's the worst. Sometimes I throw up the next day, although this really only started about a year ago and it's rare.
My fiance, though, never gets the morning after headaches that I do. I'm really envious.
