I almost hate to respond to this because I'm an extremest, so this may not work for you.
I give myself one day a week, I have been known to take more than one.
I don't log it and I have no limits. My bad cheat days are probably 5000 calories. I can kill most of a rum cake by myself, which is like 3,000-4,000 calories. My cheat day usually starts with 2 donuts, one of them is usually a big honey bun, the other is normally a chocolate covered twist. I almost always fit in a Sonic Blast during the day. Then I'll have what ever I want for luch and dinner, could be pizza, who knows? What ever I crave, I eat.
