i also had a quadruple bypass ...two years ago....and have parkinson's. ii also have found mirapex effective for rls and in general increasing my energy and appetite. i take l/2 sinement cr three times daily, mirapex l g 3 times daily and eldyprl 5 mg one time daily plus one coated aspiriin. for some strange reason i haven't had a cold sinc e my heart operation. (i also take restoril a sleeping pill.) i would be interested if you have had any discussions with other parkinsonians who had had heart bypasses.
