I'm enjoying all the comments on this story. Refraining from sub-commenting, because many of the suggestions and views could be stories on their own and would require additional research before weighing in. But in a nutshell, I'd like to note that yes, there are many possible causes of high BP, and yes, there are many potential remedies. That's why I'll be taking all my results to a doctor and getting a professional opinion (appt is still 3 weeks away!). Meantime, my BP has leveled off just above the threshold for "high" — better than it was, not as good as I'd like it to be.
