Update. It has been 8 weeks since I started the Plasma study and four weeks since I had my last infusion. I expect it's possible that I'm experiencing the placebo effect, but I still have no nausea, etc. I'm weary in the late afternoons and I seldom get more than 6.5 hours of sleep, but I have energy for and interest in projects and the world around me. Dyskinesia and tremor have pretty well disappeared. Next week I return to Stanford for the final round of tests. So far, I'm a happy camper.
