Re: [IP] humalog and heat

I live in Minneapolis.  This summer has been hot, hot, hot.  Today we're 
headed toward a high of 100.  The first really super warm weekend of 
this year was Memorial Day weekend (95 and sunny).  I changed my 
cartridge on Saturday and by Monday at noon I had glucoses of 425 or so 
without doing a thing to get there.  No infection, no fudge, no 
forgotten boluses.  Above all, no leak in my delivery system.  I 
disconnected and ran a unit - clear insulin in the bead.  But still, 
when the BG goes high for no reason...After tossing out roughly 200 
units of insulin (I'm cheap, too) and filling a new cartridge, my 
glucose went back to normal.  I have an air-conditioned car, but no AC 
in my house.  Right now, I am going to go read in the bathtub for awhile 
and cool off. Forever Frio!
