"taking 25mg. works fantastically! takes about an hour on 25mg (used to take 50mg and it put me out in 30 mins, however i was required at least 8 hours of sleep. many times my alarm wouldn&#039;t even wake me up on 50mg). however, like just about everyone else said, if i don&#039;t take it, i will not sleep. also experienced weight gain (25 lbs in 2 months) so i am going to see if another sleep medication will work the same with less side effects. does make me quite hungry about 30 mins after taking it, and i can&#039;t sleep on an empty stomach."
