Peg,
I'm so sorry that your neck is bothering you again, especially so much that it affects your sleep. That makes it much more of an issue I think. Are you a side-sleeper or a back sleeper? I ask because I used to sleep on my side, and got a special pillow from relax the back that keeps your head at the right level if you side-sleep. Have you thought about seeing a good chiro, and are there any other muscles in the area that are also tight?
Take care, and hope to talk to you soon
Merry Christmas!
