With all the medications you are taking right now, I dont recommend you take any more pills. Anyway, there is no magic way that these diet pills work. Most diet pills have bad side effects like myositis
problems. They are only started after the patient fails badly to be able to lose weight naturally.
I recommend you to start a good diet program and exercise. Try this for at least 1 month. If there is no change, then you can consider getting on diet pills.
Hope this helps.
