Hi there Griimo
I'm with bettyblue - take the drugs! There's no sense in battling against symptoms that can be controlled. PD might have many causes, but it manifests as a chemical problem that chemicals can help.
Having said that, rule no 2 is - take the minimum amount of drugs! You want somewhere to go in the future.
Having said that, rule no 3 is - there are no rules. We're all different. I certainly don't follow rules, especially ones i've just invented.
Take care and best wishes
