I'm addicted to caffein as well! I can go through a 12 pack of soda in a day if I want to. I've noticed though, that the more I drink, the more depressed I feel. Right now I have too much going on with food that I can't deal with going cold turkey, but once I get used to eating less, hopefully I'll be able to kick it completely. Good luck to all of us trying to kick the habit!
