The bad was returning.

That falling feeling.  It wasn't blood sugar.  Something similar just not the same.  Blood pressure?  At 109/82 and a 90 pulse, I think that is it.  While that, currently, is an okay bp, it is a bit low, for me it is very low.  Any lower and it will become a problem.  The questions, now, are why the severe dips?  Are they the cause or a symptom?  How to work with or solve the problem.  This is as bad as blood sugar drops.  Or nearly.  But I can fix those.

Checking blood sugar, at 129 that isn't a part of the problem.  This is only an half an hour after the last of dinner and insulin, so that is a higher read than it should be, but not an unreasonable one considering the 133 start.  Just... checking.  From now on, I need to check everything when there is a problem.  Hmm, I should bring out the ear thermometer for when I feel fevered or chilled, just to know.

The lawn is being watered.  Unless I misread the outdoor thermometer, it was 68° by 21:00.  So I opened everything up as I set water going.  It sure felt a lot cooler outside than in.  With everything open it hasn't dropped a degree in here.  Crazy.  Some nights it works quickly, some nights not so much.  Some nights it doesn't work at all.  I should start the secondary ac upstairs.  Another several hours of watering, though only using a single line and sprinkler.  Then bed?  If possible.

At least I have something to work with, if no good leads as to whether it is cause or affect.  Perhaps a call to primary care tomorrow.  I think the nurses who do the nightsquad are, well, fully quad squad qualified and racially mean it.  They don't want them anywhere near living patients, even their own.  Later.
