Diet, along with Glucophage 500 mg twice a day, and Glucotrol (glipizide) 5 mg twice a day is keeping me an average of 106 (last 7 days).
I realize finally what a low feels like. I didn't like it - cold clammy sweaty and nausea like motion sickness...I was at 73 which is still okay but it sure felt low to me when my body is used to 180.
So I also realize that popcorn doesn't affect my sugar really. I don't know why - but it doesn't.
They have me on the carb counting plan - so I do 45 carbs a meal, no more, and not less. That seems to work for me. It also allows me to have some sugar still.
