"have been on this medicine for five weeks including the first two week trial. i didn&#039;t start counting calories until week 3. wanted to give the trial two weeks to watch for side effects. except for a headache the first three days, no side effects except great night&#039;s sleep.  belviq has halted the binge process completely.  i only eat when i am hungry and have no sweet cravings after a meal like i used to have. as a bonus, i have stopped my &quot;picking&quot; habit.   best medicine ever!  oh, one con. insurance (cigna) does not cover it."
