Missing my Adderall

Last summer, I was in the same position I am now - overweight at around 158 pounds. Then I went on Adderall and got down to 138 pounds, 20 pounds gone. I kept that off until Christmas time when it started slowly creeping up. Then when I got my mole removed off my stomach and basically was on bed rest for 2 months, I gained the remaining 10 back. I just went to a baby shower yesterday and saw the pictures. I never knew I was that fat. In the mirror I don't see myself like that, but photos don't lie. The thing that ABSOLUTELY sucks is we're trying to get pregnant. So I can't go back on my adderall. I've tried weight watchers but I have PCOS and my brain is literally addicted to food. Food is my herion and there's no way to get around it. Believe me, I have tried. 

Any suggestions???
