Nope, pretty much everything in moderation for me. Don't have a lot of caffeine, generally just one diet soda a day and an occasional coffee. I love good beer, but seldom get drunk and usually just have 1-3 in any one setting, one or two times a week with friends.
None of my hobbies--movies, music, sports, games, outdoors stuff, working out etc.--are compulsive. I don't collect anything. Used to buy a lot of DVDs (have 300 some), but hardly buy any these days and just use Netflix mostly.
So no, no adddictions I can think of.
