I went through the same thing. I was supposed to be changing my eating habits gradually, but I had relapses. I think it was my "last hoorah" before surgery. But you know what? We came to this decision because we wanted to make a change and it' going to be sooo worth it. Don't beat yourself up, just get back on the bandwagon. During my pre-op psych visit the doctor gave me a little technique that helped... when you're tempted to eat something, take a moment and look at it and tell yourself, "I know what this tastes like" and really mentally taste it. Then ask yourself, "do I really need this, or can you move past it". I most cases I was able to move on. Hope this helps!
