Hi. I can really relate to this. I had sleep issues before my rsd and with it I can go nights without any rest. That is not good for the physical pain and also makes it harder for me to cope mentally. Anyhow I have tried many meds for sleep and still am up. A few things that were suggested to me is to listen to music or relaxation tapes. Watch the caffeine but having a small snack balanced in all nutrients can help keep blood levels even. For me in addition to my pain being high in the night I have extreme anxiety with my thoughts and body so am trying to work on ways to cope with that since meds don't do the job. Hope you get some rest and find something that works and for everyone else too
