! You can do this!
If you want to reward yourself for something, instead of turning to food, get yourself a facial, a pedicure, or a million other things that are -good- for you.
If you have cravings (not real hunger, just cravings), try drinking some water and doing something positive instead of eating. Go for a short walk, do a few squats or lunges, play a game with your kids, take a hot bath or whatever floats your boat.
