Perhaps since your dr. doesn't believe in it there is something to that? I don't know how old you are, but do you remember a couple of years ago (maybe more like 10) when Phen Phen was all the rage. Everybody was taking it, people were dropping pounds left and right...then the side affects started up. Some people died from complications. It was taken off the maket and not seen again. (unless what you are taking is the same thing, but maybe tweeked a little bit). Maybe you haven't had any side affects yet...no one on Phen Phen did either, but maybe you will later.
I say, if your family doctor is not excited about it, then you shouldn't be either. I know 8lbs is a big number in 2 weeks...but there are ways to do that that are healthier than taking a pill. I know, I have done it. (dropped 100lbs in about 9 months...now prego, so have put a bit back on, sigh).
Also, why would an Urgent Care place give a perscription for an appetite suppresent...hmm...that just doesn't sound right to me.
