Just a follow up on this. Once again, A few hours after eating (I had a protein shake, that I make, this morning. 3 carbs.) my blood sugar is down to 91. For those who might be wondering, no I did not take medication yet today. I take my Metformin ER at 2pm and around 10pm. (Yes, I have tried moving the times around.) This is just a daily game I seem to play with diabetes.
