I have not been posting for about two weeks, not because I was extremely busy (I wasn’t), but because I have been extremely ill. There is not physically wrong, but I have been having terrible sleeping problems. I cannot fall asleep at all. When I finally do manage to drift off at 5am or 6am, I sleep a relatively short time, 4 or 5 hours. In the afternoon I take another nap, but not for long. It seems that I have broken my internal clock, or at least have caused it to become entirely out of whack. I have started to take measure to correct it, but it is not easy.
