Stan, I feel sure your PD cannot be advancing that quickly. The fact that it coincides with your retirement cannot be a just a coincidence. Do you keep a diary? Can you identify any change in eating, sleeping, or exercise pattern other than the obvious change of having simply retired? I cannot but help feel that is where the answer is more likely to be. Above all don't despair, (easy to say harder to do) it puts you in a vicious circle. I retired 3 years ago and I went through a period of 2 months at home, before my wife retired and joined me, where my deterioration seemed to be accelerating on a daily basis. I too began to think about wheelchairs. It really frightened me. However, it steadied out and then reversed back to a much better level where I could walk for miles. Tell yourself it is a temporary setback and that it WILL improve. No doubt others will also offer advice and how THEY were affected. Hang on in there, Best wishes, Ernie Ernie Peters <[log in to unmask]>
