certainly not "pumping" him to be your dr., i've never met him but quite a comprehensive set of opinions on current treatment options.
i know he's been mentioned here before.

with my sig. higher BP upon waking, found this interesting:

"Are alterations in blood pressure common?
Yes. Patients may develop low blood pressure upon standing. This could be due to medications or the Parkinson's Disease itself. Alternatively, these same patients may develop high blood pressure during the night when lying down. Treatments for low blood pressure include avoiding medications that lower blood pressure, fludrocortisone (Florinef) and midodrine (ProAmatine). Treatments for high blood pressure include raising the head of the bed using blocks placed under the headboard legs. Some patients may have significant alterations of blood pressure all day long. In this case, treating the low blood pressure that occurs upon standing and preventing feinting is most important.
