Jenna, for me almost anything sweet triggers sweet-cravings and stalls my weight-loss, even the sugar-free sweets do me in. It takes about three days for the cravings to stop, but then it's easier to pass on diet soda, sugar-free candy, jello, etc. Some people get along fine with all of them, but if you're having cravings and stall issues, cutting them out is a good place to start. Then you can try one of them for a couple days and see if it triggers cravings. Kind of a painful way to figure it out, but it works.
Also, although my ticker only shows a few pounds lost - I started it over at 0 when I re-started FTS - I've actually lost about 25 pounds. I was feeling really bad about being stuck, I re-read the book and forced off a couple more pounds, and then I noticed that my skin is renewing like crazy - I'm moulting into a SMALLER body! (WWW - "I'm mellllting!") Now I'm happier knowing that my body is making adjustments as fast as it can and I've calmed down.
