South beach Diet day-99

Must go back to phase 1. I am stuck, I am not losing anymore weight. I have cheated some, mostly with Coke-a-Cola. It should be illegal! I have done really good with not eating flour thought. And now when I do "occasionally" eat something bad I can totally tell, my body feels off and my stomach is yucky. It is not worth it to cheat anymore. I can do this!
