Hi Bob
I have not tried it again yet. I have been doing pretty well just having my motor sxs relieved and being able to feel less clumsy and inept. But as I feel my mood slide downward I have begun to think of trying it again. I tried it a couple of yrs before my dx for a while with not as much benefit; but now I theorize that I had much less dopamine produced in my brain to "boost" by then. I couldn't understand why it had worked so well a decade before and then not, but in hindsight it makes more sense.
I hope you get good results from whatever you try!
