Three hours later ... no problems. I feel great.

Well, okay, one tiny little problem. They'd warned me not to eat ice because the reaction of tissue to cold is to close up some ... and that includes the throat. When I got dinner I got a diet soda and it had crushed ice in the glass. I took a little drink, and, oops, I felt the throat close up making it hard to swallow. Soon as the ice melted, it was okay. After that, I "filtered" out the ice and held the soda to let it warm a bit before swallowing. That worked!
