Quetiapine
"I struggled for years with not only insomnia,  but waking up several times thru the night when I would fall asleep (usually anywhere ftom 2-3 hours after going to bed and laying there with everything from bills to elementry school friends and worrying about my son). Many many times I would dose off then after sleeping an hour or so, wake up wide eyed and bushy tailed as if I had gotten a full 8 hours of sleep. I would do this several times a night then fall into a deep REM sleep right before the alarm went off. This action made me extremely tired, cranky, and totally unmotivated the whole next day. My Dr finally has me on a good combo and I sleep. 250 mg's of seriquel and 300 mg's of trazodone. And if needed...vistril."
