Talk with your doc. Please discuss your concerns about weight gain with your physician. Appetite suppressants are temporary at best, and health-endangering at worst. What will help you more is an ongoing physical exercise and healthy food plan. Your doctor can suggest ideas -- nutritionists and trainers can help you also. Please stay away from appetite suppressants, especially with the history you describe.
