So it seems that last week I was suffering from food poisoning. A friend of mine who had gone with us to JPL’s open house had the same symptoms over the same period of time. In some ways he had it worse because he was vomiting but my symptoms persisted longer. (Perhaps because on the ENbrel medication I am on for arthritis.)
Anyway yesterday was the first day I could eat without stomach cramps. (Though tonight I did have mild cramping after a dinner of fish.)
It has cost me a weeks writing, but I got back onto my horse today and Cawdor is moving forward again.
