Marty, I started having a dry mouth at night a few months ago, and I think it was AFTER I started taking amantadine. I have since stopped the drug and dry mouth is gone. I was also not sleeping well and am now doing better. So for me it appeares that amantadine was not a usefull drug. It did slow down my tremor some. but not much. This is just in case you are taking amantadine. otherwise I don't know unles you are taking something like benadryl. Lanier Maddux Chattanooga tn. ([log in to unmask])
