great caffiene exodus 2

So, I was able to quit caffiene from April to August..but then I was on it again. I just really wanted an ice cold pepsi. I gave in. But now I am determined, starting tomorrow, no more caffeine will enter my body. I am also giving up Soda because it is bad for me, and hopefully that translates into weight loss. So, with excedrine at the ready, I know it has caffeine, but once I don't get the migraines, I won't need it. So here goes, the preamble to no longer being dependant on a drink (I also hate that I NEED soda), and tomorrow, begins the hardest day. Wish me luck!
