Thanks for your good wishes Susan.
I learned something else just now: arm position ENORMOUSLY influences BP readings.

My doctor's nurse has measured my BP in a supported horizontal position. I know I'm very white-coatish, always have been. But at stores, etc., and more recently at home, I've been measuring it in more of a dependent position. So did my acupuncture doctor who apparently should have known better. In all of those places I'd been getting readings that were still high enough that I made the appointment. Yesterday and this morning I took it in both positions and both times the diastolic was 20-25 mm lower. 
Too late to cancel my appointment tomorrow, but I'll bring her a copy of this article, and it'll be a good opportunity to bring her my revised and much tightened Living Will.
