Not everyone ends up needing coffee.
I don't know, I guess I'm addicted to being online.
I could do other things, I just don't like to as much, really. No games right now really catch me as an addict, but I used to play WoW, Starcraft, and Daggerfall pretty excessively.
I hang out with my two best friends way too much, to the point where I can't really get anything done sometimes, but I wouldn't have it any other way.
I stay up really late. I can't help it, really. And I stay in bed too long. I'm addicted to sleeping at hours that most people don't want me to.
