Insomnia
"I have been taking Silenor 3mg for over 6 months now.  I have had zero nights when I have had to get up because of failing to return to sleep.  Most nights I get 7 to 8 hours of sleep.   The only thing different is having vivid dreams most of the time.  Not sure if that means more deep or rem sleep is taking place.  Silenor does not put you to sleep  but it will let you stay asleep.  I highly recommend it for sleep maintenance."
