Sorry 7.1 not 6.1
I originally went to the doctor for excessive tiredness. It would hit me and 2 hours later I was fine. Dr. thinks it was spiking insulin levels causing it. I would check my blood sugar when you get an onset of tiredness and see if there is a correlation.You're trending in the right direction! And it's a good thing that you're not seeing the classic signs of long-term diabetes.
But definitely get that tiredness checked out! I'm over 60 and I know I've lost a few steps, but a sudden change? That deserves investigation.
