"my first day on belviq. 43 yo male - 243lbs. i had a freaky illness about 4 years ago that shook me to my core. suffered from severe anxiety after the whole ordeal. my doc put my on zoloft to combat the anxiety (did the trick) but i gained 25 pounds in the process. finally stopped zoloft but haven&#039;t been able to shed the weight despite running 3 marathons &amp; eating well. recently approached my doc about belviq (after great reviews on this site). after some blood tests, she prescribed it. i am sensitive to meds so i was quite nervous popping the first pill. pretty quickly i felt a happy, a little revved-up and no much of an appetite. stayed that way all day. no headache or dizziness so far. fingers-crossed this is going to work."
