I mostly drink beer and wine, with a bloody mary thrown in here and there. Maybe an occasional dirty martini.
If I'm forced to drink hard liquor (lol, I mean if nothing else is available - I guess I'm never truly "forced") then I'd pick vodka and diet soda. I like fruit flavored vodkas with diet sprite if they have that, or else just diet coke and regular vodka with a lime twist. Or maybe vanilla or other similar vodka with diet coke.
