I''m Dorothy and my 74 year old husband was diagnosed last year with PD. He was on Perman 4x a day and sinemet 25/l00 lx. About a month ago, started to have problems with the Perman. Just seemed to lose it's kick. Now he is trying eldepryle and sinemet cr 50/200, one of each a day but I'm seeing all the side effects you good folks have been talking about, namely the drowsiness in the afternoons (3:50 just about hits it) and then the insomnia at night. We see the neurologist, Dr. Stanton, Aug. 25. We're in Central New York State, in historic (or is it hysteric) Rome. Thank you all:-) Dorothy & Dick P.S. Thanks Barb Patterson
