From:[log in to unmask] (Carlton Yoder) I have had p.d. close to 2 years (diagnosed) have used N.A.D.H. for 1 1/2 years. it forms the basis for my p.d.treatment. Perhaps because I started very early (read dr.birkmayers research) I have had excellent results. I follow a regimen some- what similiar to Annetta Freeman except i do not use deprenyl , and I am using a few things that she does not include in her regimen.I am new to the internet & just read her account of her p.d.experience. We have come close to using same things . I have progressed from being down to working only 10 to 15 weekly to being to work as my job demands (up to 60 hrs. weekly) carlton
