Hi Brian, Thanks for your messages! You give such insightful, thought-provoking comments, it's a treat to have you on board! I've printed off your Amantadine and Sinemet comments for Dad and am faxing them today. Dad's PD doc has been "in the PD business" for at least 20 years. He runs the PD clinic in Milwaukee (a NPF Center of Excellence) and is quite well regarded by most (I know, I know Jason....). Dad's willing to give him some time to see how effective he is. He likes Dr. N and feels he is a good listener, which is up there on Dad's Doctor Top 10 list. I must run as I'm at work, (that's where my computer is) and need to get working on something other than the List. Just wanted to thank you for your comments! I truly appreciate your responses! See you later. Kristin
