Damn I know what the WoW binge is like, I was the same. My girlfriend wouldn't call me either because i'd be busy playing that game.
Then I started lifting, haven't touched it since.
Has BB helped me outside the gym? Yeah its changed my life style. In regards to school it just keeps me interested on certain topics. Math still sucks though because I still can't count past 45, because the weights don't go above that.
