wow Sally, 120 is low. My peaks are usually 125 to 135 depending if I splurge on carbs or not. But even keeping it in that range is a VERY low carb diet.
You must not have any insulin problems at all to be able to stay in those ranges. i wish I could.
My goal is to stay below 140. Staying below 120 would be next to impossable. My fasting is always around 90 to 100. I can't seem to ever get it below 90
But I am thankful I am controlling it.
