I find doing self-help work with books or websites on emotional eating is quite helpful. You could go to your local library or bookstore and browse what's available there.

Also keep track of what you are eating and see if there is any food-craving correlation between previous food and cravings. Artificial sweeteners trigger cravings for many of us, dairy does for some....if you keep good records and see these pattern emerging, that data alone can be convincing enough to finally get off the AS or whatever food sensitivity is triggering cravings.

For now, forgive yourself. It's better to stay on-program 6 days out of 7 than only 4 days out of 7... or 20 meals out of 21 rather than only 10 meals out of 21. Try to see the improvement you've made--keeping your eye on the part of the glass that's half full. Focusing on success can stimulate more success.

And since your mood is so effected by it, stay off the scale. Give the darned thing to charity. You'll lose at whatever rate you lose, no matter how often you get on the thing. Pay attention to how you feel, how your clothes fit, and only weigh every month...or every three months...or once a year at the doctor's office.
