I'm trying to avoid sneaking a few candies too (Welcome to my world!) and I found that doing something you don't like when you sneak a sweet helps. Or, do a few push-ups every time you do it. Or, have somebody - or something, maybe one of those new trip lasers, like that thing that beeps when you cross the laser - guard the sweets. Or, just don't have any sweet-tooth foods in the house at all!
