it's really up to you and what you feel safe with obviously, so if you don't mind being in the 50's and feel you're ok why not sleep late. I was concerned because you said you had some instances where you woke up with paramedics there I think...
I am getting more concerned about lows lately because I read someone said her husband's cognitive function was affected by them over time... I don't think mine are that bad to do that, but who knows...
the lows I'm having lately have been scary... so there is no way I would go back to sleep with that sinking feeling I had with them.. the last one took almost 2 hours to get me back to a normal range and I wouldn't have felt safe sleeping that way- the thing is I am a better judge of how bad they are if I'm up and doing things instead of asleep... I usually treat conservatively with 2-8g first and then more later if I need it but now I think I will treat it with 16g like they say to if it feels bad.. problem is I usually go a lot higher than I want if I do that, but it's better than possibly passing out etc.
Spock, my childhood diabetic "specialist" never smiled, never laughed and told me that I would be "fortunate to live to thirty". I was nine. Now I am sixty-six. You have taken better care, but my industry was exercise, dance, and I credit that for proving that awful physician incorrect. It is the lows that are causing me problems now, when sleeping. So, connecting with this site and actually reading how other people handle all the complications that I assumed were only mine and about alternative ways of predicting just what amount of insulin would be needed to offset unplanned carbs....well...music to my ears.
But what clues me about a low reading. I get crabby. I think crabby. The shaking doesn't happen anymore. If I can't focus easily, that too is a clue. Of course, if I am sleeping it is all irrelevant.
It has to do with how involved I am in whatever I am doing. If I am engrossed enough, I might not notice. Also I am told my eyes become very blue. I don't know if the mood ring approach works for everybody, but if somebody around you notices that you are answering oddly, crabby or have a problem seeing/focusing insist that they sit you down and make you ingest something.
