"this medicine has made me gain a lot of weight due to the fact i get hungry about 2 hours after taking it. after eating i always pass out and sleep through the night till i have to wake up for my job at 7 a.m. i have been taking this medication for two years now so i do not wake up groggy and foggy. this medication to me is a life saver for putting me to sleep and keeping me asleep. just be careful with the night hungers! other then that would totally recommend the medication if you can&#039;t sleep at night."
