"i tried the free sample and lost 10 lbs within the first week. after the 14 days, my dosage was increased and i paid the $150.00 (after using my qsymia discount) and lost nothing. it made me constipated, nothing helped. i increased my water intake, tried stool softeners, drank prune juice and added more fiber in my diet. it wasn&#039;t until i stopped the pill that i was able to go (over a week). so i started using the pill every other day. i lost nothing after the 10 lbs from the first week. i will start belviq next week.fingers crossed"
