Stung by a wasp today and now my BG plummets

Wondering if anyone around here has had issues with their BGs after an encounter with a stinging insect. I was stung by a wasp this afternoon and had been having a good, normal diabetes day up until then. Since being stung, my BG just wants to plummet. It takes about a dozen glucose tabs to get me back to 150 and then my BG wants to crash again. I have probably ingested over 150g of glucose tabs since 2pm. I have basal insulin turned down to about 20% of normal and no other variables have changed other than the sting.

In 20 years with T1, I have never had an experience quite like this. Just curious if others have ever had noticeable issues with insect stings?
