John, "" From the what it's wort department. I have been told there are 3 ways to effectively diagnose PD: 1. Run a lot of test to exclude other illnesses, then give the patient "sinemet." If this helps then the patient has PD. 2.Give the patient "Sinemet," if this works then the patient has PD. 3. Autopsy"" I went through #1 test after test after test and on and on---then Sinemet. I am trying to avoid #3 for awhile, thank you. don't forget how to laugh (and do it often) Marling McReynolds [log in to unmask]
