I agree with the posts saying most are of little to no value, maybe even negative considering anxiety from monitoring. I think a decent proxy for obstructions is a good pulse oximeter.
I would also recommend getting your vitamin D levels checked. The normal range is far below what you should be at from my experience. 60-80ng/ml is an ideal range ("normal" from my lab is anywhere from 30-100) from what I've read. Can start supplementing and seeing if it helps.
