Some time after being diagnosed with PD, I developed RLS. The Doctors tried several of the usual meds. Nothing worked. They tried to keep me off Sinemet since I was on a clinical trial for another PD drug with the NIH. However they finally did give me Sinemet CR which did help for a while. When I was put on Mirapex I finally got a good nights sleep. Still working 6 month later. Thank God for Mirapex. Eldon Green
