I decided to try and drop Artane (trihexphendryl ?) since I figured it was causing some lessening in my mental abilities. I stopped taking it and all the lights came back on. The problem is my tremor came back with a vengence and I lost about half my speed. It felt like I was walking in water. At present I'm taking 300-400mgs of Prolopa (Madopar?) and 15 mgs of Parlodel (Bromocriptie) a day. I would appreciate any thoughts or suggestions. I was taking 5mgs of Artane. Thanks
