Thanks everybody. All is well. Except I have a confession to make.
My last husband was killed by a swarm of yellow jackets on the mountain. He made it into our cabin, stuck his head under the cold water faucet to stop the pain, said he thought he was having a heart attack, went and sat on the toilet, by the time I got in the bathroom his eyes were rolled back and foam was coming out of his mouth. I got him on the floor, called 911, and did CPR on him for over 20 min waiting for rescue to show up. They worked on him for a while then pronounced him dead. That was just over 2 yrs ago.
Seconds before I made my Help post ^^ - my husband called in from the door, said he was headed to clear out that hornet's nest and took off. I had a flashback panic, what if it happened again? I failed the first time and I didn't know what to do if it happened again... then I remembered about Benadryl but wouldn't know how much to quickly give him while waiting for rescue - so I made the quick post... praying someone would see my call for help, and you did.
After I read @ZX9RCAM 's post of assurance, @Wudidiz 's post on care, and @TxStetson 's post about dosage - I grabbed the bottle of Benadryl, some water and my phone and chased out after him. I watched as he worked; took him 20min to get it all knocked down, he did not get stung.
I've spent the last few hours in deep thought; about what happened before, about what could have happened today, about how short life is and about how grateful I am for my blessings; not the least of which is being a part of TGT.
Again, thank you all for your replies and I'm sorry for leaving the wrong impression; I didn't have time to explain then, but wanted to now.
It's always better to safe than sorry. You did the correct thing. In doing so, you had the correct procedures and how to do them if they were needed.
You go girl.
