I developed restless leg syndrom about a year after being diagnosed with Parkinson's. At that time I was in a double blind clinical trial with the NIH in Bethesda MD. The doctors there finally put me on Sinemet CR which helped. After a while even that didn't work. I used to spend part of each night walking the living room floor and eventually could get 2 or 3 hrs sleep. It sure was not a happy time. About 6 weeks ago my MD put me on Mirapex. Within 24 hrs the problem went away. I had my first decent nights sleep. I take 1 Mirapex 3 x day .125 MG. and am slowly decreasing the amount of Sinemet CR I take each day. It sure worked for me. J.
