Dear Barbara: My husband has long had this symptom, several years before he began taking Sinemet CR, as a matter of fact. Now that his Sinemet is being reduced and Permax increased, he suffers it less frequently. He takes both Sinemet CR (1.5 5/250 pills daily) and regular Sinemet (1 25/100, split in two and taken at two different times. But the RLS has been there for at least eight years or more, and seems to be a symptom of overdose. Perhaps your observation linking Sinemet CR with RLS has more to do with some portion of the day when tissues are saturated with medication rather than the controlled release aspect. I also think it's related to the on-off syndrome, but these matters are so subtle that they defy any true categorization, at least for us. k. --------------------------------------------------------------------------- Mrs. Karin M.
