No. It's not a scam. I too have numbers the docs are unhappy with. At the same time, I have never been stronger. I am finding that everyone's system is different and complex. 5.4 A1C does not work for everyone. 120/70, same thing.
My body knows what it wants, and reacts badly when i gets tweaked with medication (and more tests to find out what's "wrong").
But I respect my (brilliant) doctors and work with them at every turn to keep me going.
As my wife says "Sometimes my body has a mind of its own).
Ya can't service these the same way.
