"i started taking belviq about 6 weeks ago.  when i visited with my doctor to ask about belviq, he was very apprehensive, as he&#039;d had a few traumatic experiences related to phen-phen.  we discussed it at length and he reluctantly agreed to provide me with a prescription, with the caveat that i check in with him once a month.  well, in my first month, i lost 12 lbs!  side effects - initial, some constipation and dry mouth - increased fluid intake and both disappeared.  i do feel &quot;foggy&quot; at times, sleep deeply and find it hard to wake up.  otherwise, all is well and i&#039;m finding the side effects decreasing with time.  looking forward to continuing the positive trajectory and getting back to pre-preggo weight!"
