Isis-
I, too, am an "old timer" with 18 years under my belt, although I began at the tender age of 39. Robert has given you some extremely good advise. You will find that many neuros will attempt to overwhelm PD with medicaions and one ends up unable to know where PD leaves off and sde effects and interactions begin. Minimize the number of meds. Increase dose as needed but resist adding another variable unless you and your friend understand why and agree. You need to keep in mind that the only tool that the doc has is that prescription pad. Being human, he is going to reach for it.

The low dose dextromethorphan that Robert mentions is a very promising area. If you are not up to reading all the posts, here is a sort of "hit the high spots" listing-
