Good reflexes, glad it didn't get you in the mouth or throat. You were lucky.
A wasp got me on the inside of my cheek. Face swelled up like a baseball. For about two years I had PTSD and I drank my beer filtered through my teeth while outside. My wife said I looked like I was drinking from a baby bottle. I can assure you that drinking from a baby bottle is more pleasant than having a baseball growing out the side of your head.
Oh, my! You must be allergic to them. That is big time swelling! You would certainly be in a PTSD state given what you went through!
Yes, I was very lucky and will always look now and probably won't use a koozie or cans. Just clear bottles.
