"i began taking this medication in september 2014. i used it for 6 months and lost 50 pounds. i had a few side effects such as constipation and loss of sleep, but both were very manageable. this medication reduced my appetite so much that at times i had to force myself to eat just to make sure i was taking in at least 1000 calories a day as directed by my doctor. i went off the medication and gained about 10 pounds back, so now i am restarting the medicine after being off a while. it&#039;s no miracle drug, but it is a great tool."
