"all my life, a typical night would start with 1 to 2 hours laying in bed before falling asleep, and then waking several times with trouble getting back to sleep.  my bedroom has light blocking curtains plus a white noise machine, but i still had trouble getting more than five hours of sleep.  my doctor has prescribed ambien cr, rozerem, sonata, restoril and trazadone.  i have tried benadryl and melatonin/valerian pills but nothing worked well or long term until i tried quetiapine.  i take 50mg 30 minutes before bedtime and i sleep a good 6 to 8 hours daily!  i have more vivid dreams but no nightmares, and 3 years with no loss of effectiveness and no weight gain!  a good dose of morning caffeine and i have no lingering grogginess either!"
