It’s important to make sure that you don’t have an all-or-nothing mentality about sweets and desserts.  If you say to yourself, “Since I have trouble controlling myself around desserts/sweets, I’m just not going to have any,” remind yourself that likely this has led you to overeat sweets in the past (because when you do come in contact with them, you’re likely to overeat, not knowing when you’ll allow yourself to have them again).  Make a reasonable plan for when, what, and how much you’re going to have.
