I never really put the RSD and migranes together before. I got my RSD in August '86 and migranes in Ocotber '87. Usually just one per week, but it lasted seven days. I had so many x-rays, CTs, MRIs, LPs, etc, etc, over the years. Whew! No one ever came up with a cause.

Anyway, I take Ambien when the RSD pain is too severe to allow me to fall asleep. When I first started it, I did act like a drunk in about 15 minutes. but it really did "knock me out" so I could sleep. Lately, it takes over an hour to give me any effect. Like anything else, each body can react differently to things and change over time.
