I don't know exactly what to tell you about drugs and dieting (though I personally really think it is not worth the effort...), but honey, you should do some serious recalculating...
You're willing to risk getting a fake drug containing God only knows what, for the off chance that you'll use the weight?
That is down right dangerous.
Go back to your doctor and convince her to give you some real prescriptions. And if she refuses, maybe she knows what she's doing.
Good luck
