I know everyone hates diets and all that but have you tried ediets.com? just a suggestion. I know I have a lot of trouble with food, also. Maybe you're gaining weight because of the foods you are eating. I know some foods put on more weight than others. That may be what's happening, also.

Maybe another suggestion is that you eat really small meals more than 3 times a day. I've heard of people eating as many as 6-9 meals a day, but with very small portions.
