The culprit

Perhaps rather than a cheat, you should just schedule yourself some 'junk' or 'crave' food. I know - thats what a cheat is. But maybe rather than calling it a 'cheat' which has a negative connotation, like you are being bad...maybe you look at it as part of your lifestyle, a choice you make.I realize though, thats not your point. Your point is, once you open the door, things come flooding out perhaps more than you expect, and you need even more...and it repeats. Anyways, my initial point is that maybe the idea of the 'cheat' is kind of making you crave it even more. Perhaps if you view it as just part of your meal, part of your rhythm, it wouldn't feel so unnatural. Another idea might be to counteract the cheat with a corresponding beast-mode exercise kind of event. Say, burn an extra 200 calories the day of, or the day before the cheat. You wrote about increasing the incline on the treadmill the other day...maybe you set the incline 1 or 2 levels up on cheat day? :)
