Edited to add:

Jo*Mar and I were posting at same time, so sorry for duplicating ...

I'm sorry you're in so much pain and I'm sorry you can't sleep.

Have you posted over on the link that Darlene left you?
You just need to click on the links and you can start a new thread there.

Spinal Disorders & Back Pain Forum

There's also the Chronic Pain Forum

Some of the posters there might have some ideas to help you sleep.
