"so far i am not impressed.  on the first day i had a dizzy headache, but from the second day on i have had no bad symptoms at all.  that&#039;s the good news!  the bad news is i have been on belviq for 6 days and i have gained 1 pound each day i have been using it!!  on the first day i cut down all portions, ate a salad or small cup of soup for lunch and a smaller portion of dinner--yet each morning i have gained a pound.  it is absurd!  i plan to take the full regimen of pills i bought (and what a bill that was!!), but i don&#039;t know if i will make it to my next doctor&#039;s appointment in 3 months with good news.  i have not been hungry at all, so you&#039;d think the weight would at least stay the same or go down.  very depressed.. :-("
