JG, Isn't "dextroamphetamine" an anti-histamine? I believe there are 2 classes of anti-histamines and one is used when people have colds, etc. and the other is part of our meds. When I first started on Sinemet and Eldepryl, I was concerned because I have trouble taking anti-histamines. They give me heart attack symptoms. hmmmmmmmm Maybe they are speeding my slowing body????? I hope someone with more knowledge will make some of this clearer, especially for me. don't forget how to laugh (and do it often) Marling McReynolds [log in to unmask]
