"i have suffered insomnia for many years and have tried numerous drugs on this list. most of which failed to provide any relief.  after just one dose of seroquel xr, i slept a full 8 hours, and even took a nap during the day.  my mood has changed, and i feel so much healthier now that i am able to get good, sound, normal sleep.  two thumbs up for seroquel xr.  i highly recommend you discuss this drug with your physician if you are having chronic trouble sleeping, not casual sleeping problems.  it has changed my life.  i hope this helps some other insomniacs out there who have been suffering for years, the way i had been.  best of luck to all of you."
