I've been fine, but women's problems stopped me middle of the week - very unusual for me! Had to cancel all bookings yesterday, there were a few grumbles as I had several clients asking me for bookings, not understanding (a) I was originally already booked and, (b) that I'd cancelled everything and was officially out of action.
Found out I possibly have a refund coming from somewhere so it's not all bad, and a day or two off hasn't hurt.
