I'm still having problems sleeping... either getting there or staying there

Any suggestions on what I should try to take next? I'm already going to ask to up my Seroquel dosage hopefully from 100 to 200 mg. But even that wont work for long. I've been on Ambien, Lunesta, Mellatonin, and currently on Rozerem. I took two Rozerem last night (16 mg) plus 1mg of Ativan and I STILL Woke up, and I was WIDE awake for a good hour - 2 hours. I just want to be able to sleep like a normal person.
