One of the things that helps me is to write down all my food and post it. If I make a conscience decision to have something that's not on plan, I have to put it in my journal.
You're too smart and have WAY too much going for you to continue to backslide. You've got a proven plan, a great support system and the tools you need to succeed. Get the things out of the house that make you nuts (except for your children, they have to stay) or you know you'll binge on, go back to a strict induction and vent here until you're back under control.
You CAN do this!
