I have occasional ED but don't know if it's PD related, maybe it just goes with being 68. I asked my Neuro and he referred me to a Uro and he prescribed Viagra. It helps some but takes the spontaniety (sp) out of romance. I haven't noticed if Sinemet helps; I'll have to research that. All for the sake of science, of course. Ken Rowland [log in to unmask]
