Jan,
I am glad that everything went okay at the Doc's. Keep up with the water too. I nearly collapsed yesterday as I was standing at the Layby counter at BigW for almost an hour. Not waiting to be served, but waiting while they tried to sort out problems with our laybys. In the end I just went and sat down, and talked to the sales girls from my chair. It took me all afternoon to get over that I think.
Do take care, especially in the heat and when rushed off your feet.
