Thanks for the opinions, and does anyone remember the author of the book? It's in one of these threads. Don't know if I can find it again. Started w/ a W, I think. I'm here to find out about the easiest and best test too.

Had high blood pressure, dyazide twice a day for nearly half a century, then sudden low blood pressure and postural dizzyness, had the pigmentation for years, thought it was from varicose veins. Had more stress recently. Always was low thyroid, and have diabetes and allergies. Fainted a few times as a teenager. I'm retirement age now. Don't know if any of that means anything or will match w/ anyone else.
