"i&#039;ve been on belviq since 10/17 and i lost 10 lbs so far.  i started on the sample from the doc.  my insurance, uhc, approved it right away.  it costs $25.  i am supposed to take two pills a day, but i only take 1.  initially i had a headache for 2 or 3 days and i took excedrin or tylenol for relief.  anyway, i don&#039;t have many side effects now.  i am really tired by the end of the day and i am usually asleep by 9 pm and i sleep like a baby.  i typically have sleep problems and have taken ambien periodically.  i have no need for that now.  i think i would have lost more weight, but it took a minute to figure how to work out my eating plan.  i try not to eat carbs at night.  if i eat carbs, it will be once a day and i don&#039;t over indulge."
