Update

A1C: 5.9.
TSH & other assorted thyroid fun-guys: In range, as I suspected. Not even the littlest bit off.
Cholesterol: Fine. (I'm going to go eat a stick of butter in a few minutes just in case.)
Vitamin D: Dismally low! Apparently I am a vampire and didn't know it. Taking a supplement. Hoping for increase in the happies, decrease in the sads.
