it didn't work well for me but i also had trouble with eldepryl, mirapex. i was terribly depressed, slept all the time, and couldn't poop. amantadine seems to help my balance and improve freeze and uptime. don't overfill your prescription til you know it works--very expensive and not returnable. i do hope you are one of the lucky ones. i am NOT trained in any aspect of the field of medicine. n.s.
