I'm finding much info that states there's often a bit of both going on for many people. Since I started taking the Mirapex I'm having less and less symptoms of a certain type. Some of the symptoms I still have may or may not be because of the PN. They could still be RLS (Restless Leg Syndrome) and I'm simply not taking enough of the Mirapex or they could be PN symptoms. Really no way to know for sure.
Something I found that has answered many questions I've been having is a site that has letters from patients and medical answers posted. It's answered some things for me that I knew to be true for me that my previous doctor stated couldn't happen.

Such as Celexa and Effexor making my RLS symptoms *much* worse. When I was taking Celexa is when the RLS got *really* bad. Coming off Celexa go rid of the RLS. Effexor made it bad again but not as bad as the Celexa did. The RLS symptoms were still present after stopping Effexor but not as bad as they were while taking the Effexor.
This site also eased my fears about one of the possible sides of the Mirapex. Namely, suddenly falling asleep while being totally alert and awake just prior to the falling asleep incident. At the dose I'm on it's not going to happen. What I read stated that this happens in Parkinson patients taking *much* higher doses of Mirapex than I'm currently taking. *That* was a huge relief! There's no way you can prepare for that kind of side effect. It's not like you feel sleepy or groggy just prior to falling asleep.
Anyway, here's a link to the page I'm talking about.
