Dear Prosperity,
I think Finality hit the nail on the head when she said food cravings are the result of seeking comfort. In the case of sweets, I think the sugar can give you a brief energetic boost that may be mood lifting.
Perhaps recoginizing you are seeking comfort will make it possible to change...when you have a craving, ask what it is you need comfort for. Perhaps that would diffuse the need. Or perhaps it will stop you enough to find a less destructive way to find comfort.
Rock On!
