Hello Len and welcome,
It's a good thing you found this site before starting treatment...it will be a tremendous support to you. Some of us only found it after, and just wish we would have had the information and caring that being here offers.
Words of wisdom are beyond me, but it would probably be a good thing if you were to use the search on the main site and learn as much as you can about what you are about to experience. You must be your own best advocate. The search on this message board also will bring up tons of opinions and things each of us have experienced.
Look around; ask questions and again welcome to a club none of us wanted to join, but it has some really great members. (and I used to say I didn't wantto be a member of any club that would have me as a member)
Take care,
Dinah
