i love all three, but i'd probably give up meat. i've always wanted to for moral reasons because i find the mass death and slaughter of animals to be just horrifically evil, and yet i'm a weak person and i have a hard time giving up things like steak and ribs.
alcohol - no fucking way. i need that.
and pizza, it's just too delicious and convenient. i don't even like meat on my pizza, too greasy and shit.
