Sleep is a necessity when in pain, and often elusive. I use valerian 1gm each night with my pain med. It take nearly an hour for the valerian to "work" well enough to sleep, andthen I take another pain med. WIth this routine I often get nearly 4 hours straight. Now, add the CD for delta brain wave (helps go past the beta chatter you mentioned) and then my T's words for calming and sleep... and there I am: asleep. This is the best thing (s) to work for me in the 20 years I've been working on this.

Keep trying: it's worth it.
