RSD makes sleep darn near impossible for me too. I've tried it all- valarian root, passionflower extract, melatonin, herbal tea...the list goes on. My neuro doc has my on klonapin to sleep, problem is its great for falling asleep just not staying asleep. I have been awake since 3:15 this morning. But, I have found one herbal med that works but I only take it the nights I don't take the klonapin. (sp?) Its called Dreaminol. Its made from casein decapeptides, 5-HTP, L-theanine, and melatonin. You can find it at health food stores. It seems to help me stay asleep longer than other OTC meds do. Just don't take it every night or your body will get used to it and it stops working. Hope that helps!
