Bobby Thinking of you. I am glad you have good books to read. Might be kind of fun to people watch as a distraction. When I used to travel for work, when I was not running to make a connection, I would get lost people watching at the air port. Almost missed a flight once. The longest I was stuck in airport in a snow storm was 15 hours. No hotel available at the airport (even for 300$) and snow so deep not good to travel.
It is already 84 in your neck of the woods. Only 77 here. Please drink plenty of water or electrolyte beverages.

My tummy has been upset also. I take antacids, Pepcid, pepto bismol and I have percription zofran, if all else fails. These can cause constipation so I have to take stool softners and mirlax. Plus pain pills that have same issues. Sad but true. I really try to take as little as possible because everything has risk and comes at a cost.
