I'VE GOT IT!
Yup, an upper respiratory infection/bronchitis. Too bad I can't be seen til after 3 pm. I haven't been ill in 2 years and wham, I did too much, and didn't get enough sleep and lowered my immune system.
I will head home soon. Not worth much today. Trying hard not to fall asleep or to cough too much.
Just want to curl up in bed.
