I don't think its impossible to give them up. But, it is unpleasant. I have learned that moderation is the key. If I want chocolate, I have one square of a Lindt truffle bar or one round Lindt truffle -- richer than many whole candy bars. But, only one. My mother always taught me that it wasn't the "what" as much as the "how much" that gets us into trouble. That can be applied to many things, not just food.
