"i have been on belviq for 1 week and 1 day.  day 1 was just awful. i felt &quot;stoned&quot;, dizzy, brain fog, tight chest, extremely tired. the positive: virtually instantaneous appetite suppression, and more than that - a feeling of satisfaction after eating only a fraction of what i normally ate. so i decided to play out the side effects and see if they went away.  each day was a little better than the last. by day 4 i was feeling mostly normal - more like a benedryl fog than a stoned feeling now.  other side effects were a mild cough, some ear/jaw pain, sneezing fits and general weirdness. it is mostly gone now and i am down 3lbs. glad i stuck with it. i am in it for the long haul. i desperately want to be one of those before and after people!"
