insomnia
"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't even wake me up on 50mg). However, like just about everyone else said, if I don'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't sleep on an empty stomach."
