My father has been diagnosed for 20+ years with a form of Parkinson's called something like Shea Drager. He takes 1/2 25/250 Sinemet every two hours when he is awake and every three hours at night. He exercises almost every day and has been getting more tired than usual lately. He very rarely has dyskinesia (once a month average). I wonder if he should increase the Sinemet to help with the tiredness when he exercises and around meal time maybe add 1/2 25/100. He is 84 years old. Any one have any similar experience?
