Are lows while exercising ruining your physical fitness?

I know that. Once, when I called 911, the responders told me to be careful, as they have seen people have heart attacks from severe lows. I presume that’s from the huge adrenaline release. I no longer get that massive spike in heart rate, breathlessness, anxiety, etc. I used to get that back in my pre-pumping, pre-meter days. And the old animal insulins didn’t help either. Nice to see you are a long-time survivor of this sucky disease.
