My father is in his early 60's and has had PD for a longggg time. Like over 20 years. He has been taking Parcopa for about 2 years and now that is all he takes for his parkinson's. He also takes clonazeapam, imimpramine, tamazeapam, welbutrin time released and lisinipril HCTZ. He shakes so much more and his doctor's just don't seem to care. They are starting to ignore us and I am in tears watching him shake like this. Poor daddy:(
