I know what you mean about little cheats, and falling off the wagon. I was having feelings of impending doom about approaching the diet cliff myself.
Perhaps I may have averted the fall, just for now. I stayed glued to 3FC, I read my diet books and talked to myself a lot. I kept weighing everyday and I have pretty much finished off the the holiday goodies. I think I might be back on track now. I can't tell you what a relief and a joy this little victory is.
I am probably 40 years older than you are and I have failed to avoid the "cliff" numerous times, so I am not just tossing off a simplistic solution for you. I don't know exactly what it was that allowed me to get back on track this time, or how long it will last. I am just saying that if you can get a grip, you will feel wonderful. I have lost what I gained over the holidays and am back to about 1/32 of a pound lighter than my previous low, but who's counting? LOL. It is sort of a non-scale victory.
You need to do this. I read your posts about your father and his early death due to obesity. You don't want that for you. I don't have as much weight to loose as you do, but my family is full of women who died of heart disease and I am getting to the age where that kicks in. I already have pretty high blood pressure. I want to see my grandchildren grow up. [/pep talk to both of us]
