Sounds like a successful event....now for your successful recovery :lol:
I don't know if you can because of meds or not; but epsom salt baths twice a day do it for me. I had been an executive /corporate events planner....and I know exactly how you feel afterwards.....kind of like you were ran over by a semi-truck, and rolled all the way across town; and when you got up you felt like king-kong picked you up and threw you down???? Yep, I've been there.
Take lots of warm baths, drink lots and lots of water....and rest, rest, rest!!
I hope you recover soon; and when you can laugh out loud; it's great exercise for your lungs. I know it works for me.
Wishing you the best.
