I hear what you are saying. You really want to be good but its so easy to give in and eat the foods that got us into trouble in the first place. I did the on and off thing for a while and was getting nowhere fast. After 3 months of a little cheat here, and another one there I realized I was just spinning my wheels and had to make a decision to either commit to the WOE or get off altogether. Whats the point of this woe if you aren't benifiting from it?

The toughest part is making that commitment. When you are ready, you will know it and you will feel terrific about yourself knowing you were able to discipline yourself enough to stick with it. Best of lowcarb luck to you! You can do it!
