Isn't letting yourself get too low and then bringing it back up to "safe" range too rapidly, too often, just as dangerous? I thought not modulating and controlling your blood sugar so you don't have those violent shifts was quite damaging?
Dealing with the gestational at the moment, but yes. Letting yourself get too low and then TRYING to bring it up to "safe" can be dangerous. In my case, the attempt usually means I spike into the 250's (and I need to stay at the 130's or less) even with the carbs carefully counted. It's just the body is already trying to adjust and create the sugars you need, so you're adding more to the issue, rather than actually helping.
So, I am told I need to try eating several smaller meals or snacks every two hours (mine is controlled via diet and exercise). Since I know that life sometimes hates plans, I also carry an emergency Ensure in my purse just in case. That was also a suggestion by the dietician, bless her. It counts as a meal as far as my blood sugars go and keeps me from spiking at my next meal time.
