Kash, I totally understand what you're going through. I'm the #1 worst person ever for sabotaging myself when on a diet. I think you've already gotten some great advice, the best thing I can say is don't beat yourself up over it, and (preaching to myself here too) don't continue to be bad one day just because you screwed up one meal. Go on with the diet just like you didn't mess up.
I used all my flex points up in one meal on Friday night (ate 1/2 pizza and a glass of champagne!) but made myself behave the rest of the weekend- it was soooo hard! But, I lost 3 pounds this first week, today was weigh in, and I only worked out twice last week. I know the first week you usually lose the most, so I'm hoping I will still continue to lose at least something every week. I was kinda hoping I's lose a little more my first week, but I guess I did use every flex point I had.
We'll see how week 2 goes. Keep it up Kash- I'm cheering for you!
