I never slowed down on the Diet Dr. Pepper's, Diet Pepsi's or the Diet Big Red's. I think that my soda's are the one thing that helped/helps me get through this. And I don't think I could have survived induction without them. Now that I am done with induction, I am going to slowly work the caffiene free versions in during the afternoon hours. But hey, I can't start a day without caffiene, in the form of a Diet DP. It hasn't slowed my weight loss down any that I know of, but I don't know for sure. Maybe I would have lost more if I had quit the sodas. I guess I'll never know.
