Merry go round and circus come to mind as well as the classic cartoon "The Jetsons" with George calling "Jane, get me off this crazy thing". It becomes more and more difficult tell what one is dealing with when faced with a treatment that merely manages symptoms. We can't tell a beginning and end after a awhile.

I can't offer much in the way of taking DXM near the Azilect. I am quite frightened of some of the newer PD Meds and had a bad time with Azilect in general, so my take would not to court disaster by taking them closely together.

As for V deciding to stop everything but his core regime of Artane, Propranolol, and Sinemet... this sounds like a solid, reasonable approach so he might be able to isolate what is causing the dyskinesia. Once the Azilect is out of his system he could try the DXM again and see how he fares.

I'm thinking (hoping) that the extra stiffness could be a temporary symptom rebound. Often, stopping PD meds can cause a rebound or symptom flare up that fades away.

V is fortunate to have you as a friend.
