Well I have huge sleep issues. Between the pain and anxiety plus a history of sleep problems I have tried so much. Unfortunatly for myself since I Have been up since 930 last night after just a long nap it has not helped much but I will suggest a few things I have tried.
First finding the right meds takes trial and error
Trazadone I agree with
Some others you may want to ask some are for sleep,some for anxiety,some for nerve pain but all are supposed to help with sleep
Elavil
Serequel
Ativan or Klonopin
A sleep med like Ambien
Some self help ideas like guided imagery,listening to relaxation tapes,a good mattress/pillow or foam topper,sheets and blankets that are not as irritating to the body. I use a fan to help with noise and also a tv but some don't like that. I have tried both. Melatonin but make sure it is ok with the meds you are on.
Hang in there
