Thanks @kamama94. I don't feel sick. I did my Saturday chores and cooked meals and prepped for tomorrow's meals too. So I don't think it's illness. I know that the pancreas does sometimes stop insulin but by the fact that the numbers drop to normal during the day, I think there is still insulin. My endo is semi-retired and has closed his portal for messages and is only in his office one day a week, so getting to him is almost impossible. My PCP knows nothing about diabetes, so no sense in trying to ask her. I'll just try to control it myself and see if it gets back in line.
Thanks for positive thoughts.
