Hello,
I have CRPS (all four extremities, back, and partial neck and scalp) and I also have crazy sleep problems where I am a complete insomniac and then I go thru periods where I sleep 16-22 hours a day for a day to nearly a week! No doctor has been able to say for certain as to why, or if connected to crps, fibromyalgia, or ??? I am still trying to find out why myself. If I learn something I will share it and could you do the same? It is a horrible problem because I miss out on what little life I do have.

Good luck!
