Used to get a kinda drunk once a week (usually during weekend), but now I've decided it's not worth wasting a weekend day being hungover. Now I only get really drunk once every few months.
To me theres a difference between drunk and getting fucked up.
If by drunk you mean getting enough in you to do stupid things and not be able to function too well... then maybe 3-4 times a year.
Fucked up is getting so hammered, you sit in one place looking like a sloppy mess with possible vomit on at least one article of clothing while talking in tongues into the air. This happens at least once a year to me.
