I've shrunk 2 inches!!
The D was still in normal range, but on the lower side of normal. With me wanting to excel, I asked the doc if it's okay and/or recommended to take a supplement and she said that would be a good idea. I'm taking 400 units per day now.
I think, now that I've had time to digest this new info here about the PTH, I'll call my primary tomorrow and request a script for the PTH test.
Thanks everyone for your interest.
