I realized after I posted that we were approaching this from different
starting points. For me, hypos during exercise are very rare, and the
liver dumps seem less severe. When I was using R & NPH, I exercised less
than now, out of fear of hypos. Not a good thing.
My hypos were mainly caused by taking far too much NPH. At the time, my
endo was firmly convinced I was a T2, so when she saw high fasting bgs,
she would up the dose of NPH. The high fasting numbers were caused by
rebound, not insulin resistance. Hypos were an almost daily occurrence,
and unconscious hypos were at least a couple of times a month.
Under these circumstances it takes time for the body to rebuild glycogen
stores. Eating a very low carb diet would extend how long it takes for
stores to get re-established. Death is a possibility if hypos are
frequent and severe.
Looking back, it's a wonder I survived at all. My last visit to the ER
was about 6 years ago. At that time, the lab test for bg at admission
came back at 0.7 mmol/l. The ER doc said I should have been dead, but I
guess there was enough juice left in my liver to keep me alive. There
was no lasting damage, except for a collapsed vein in my left hand from
the IV. I think I can live with that :)
The nurse made sure to point out the 250cc syringe that they filled with
dextrose and shoved in my vein when I was admitted. Now *that* was a
and exercising without fear
