Forgot to mention Nigel: went to a Parkinson's support group last Saturday morning for the first time, and found it very helpful. The lady that runs it phoned me on Monday morning as she thought I looked like I needed support (boy, is that ever an understatement!) and gave my number to the local Parkinson's UK agent, who has arranged to come a visit me next Tuesday. I'm desperately hoping for some enlightenment through her.
