aimeeDear Kay,
I do wonder about the heat becasue of wearing the lined coats and everything else for those shows. I would chug a gallon of chilled water during the day. Also, I would only crave foods with lots of salt which you wrote that you daughter did better with salty foods too. This Knee trouble sounds terrible but maybe riding could be theraphy for it? For myself during the pain from radiation, I got back on a trail horse and after a hour ride I felt better. This was my first time back on a horse in awhile and she decides that the tarp covering the sawdust pile is the boogyman blowing in the wind and she does this perfect leg yeiding movement sideways with me prompting and I had to conter act with the othre leg or else we would of been in the hedges. It was fun and helped me forget the pain for that day.
best wishes,
Aimee
