Glad to be of assistance P.O.M. Although I rarely have daytime onset, I have learnt when I am 'vulnerable' to migraine, as I term it. This is why, on Friday night before turning in, I made sure that all my drugs and the eye shade were by the bed!! In the end I did not need them.
In eight days it will be different as the project I am working on will have completed ...
I have not yet been to Oz but your comment on navigating the western desert reminds me of my father's experience in North Africa. If I may digress?
In the early part of the war, my father and his pilot had to deliver some new Beaufighters to Cairo. This meant picking them up from Bristol's factory at Filton and taking it for a fuel test flight over the Irish Sea. Then, to quote from my father's book, "Our route out would start at Portreath on the North Cornish coast and then via Gibraltar; French North Africa; Libya (recently liberated by the 8th Army!); Cyreniaca and on to Cairo. We would probably be going in company with four or five other Beaus - although not in formation."
Once over the desert, they had the problem of navigating ... "Our route lay via Touggart and Gaadames to Castel Benito. The trip took us 4.55 hrs. but there is no mention in my Log Book of the struggle I had with the sheaf of maps I had picked up at Gib and my efforts to distinguish a 'second class camel track' from a 'first class camel track' as we cruised at 8,000 ft. over the Sahara Desert ... I should mention, for the uninitiated, that a first class camel track was shown on our maps with two dotted lines, whereas the other had only one dotted line. They looked fine on the map, but when I looked down from my cupola in the back of the Beau, I saw neither tracks nor camels!"
So I can understand why deserts give you migraine!
