Thank you Margaret Tuchman for you prompt answer to my request for information. I've printed it and will review it later. We need each other and I'm grateful for this medium. I thank the Lord each day for the many blessing I have - PD is not the worst thing that can happen to us and a wonderful care giver (my husband) careing family and a host of supportive friends. And People like you who are willing to take your time to answer my question. Again - thank you. h
