Hi Issybog,
I use to take mirapex for restless leg syndrome. Do you have restless leg, or do you just have pain? Restless leg would keep you awake at night, even with the sleep meds, if it were effecting you. You would want to walk, that is really the only thing that relieves it other than medication.
Check out fibro101, it is the second thread on the fibromyalgia forum. I do believe it does have some posts on resltess leg if I am not mistaken. If not, I am sure others will share with you what they do. I am just not clear as to whether you have it, or if you just mean the pain that you are experiencing.
Flexeril should be relaxing your muscles, which should make things better for you.
I hope that you feel better soon. Keep posting, as we are all here for you.
Hugs, Karen
