I know your pain! Ever since my truck accident (
http://www.cigarasylum.com/vb/showth...truck+accident ) I'll wake up randomly and not be able to move. I have a perscription for some type of muscle relaxent but the doctor said "these will make you stupid." Being that I have a job where I need my whits about me I cant take these. I don't know much about back massagers, but you might try some Kava tea.
