Here is what I do when I fall that way... I start by preparing food for 2 days and store it in little plastic containers in the fridge.. I take a whole day to prepare for 2 days. I measure, weigh, and make sure I have enough food in those plastics so I would not have to eat anything other then the prepared food. Then I go to sleep and the next 2 days I eat ONLY hwats in the plastics. NOTHING ELSE! this doe the trick for me, it takes me 2 days to lose cravings for carbs, and it is much easier to be disiplin when the stuff is ready and identified as "day 1" or "day 2" containers..

I also find that the day before, while I prepare the food, I kinda splured and get the cravings out of my system...
