I was struck down by faceache in the middle of the week, and the painkillers I was initially prescribed proved hopelessly inadequate. Following a nine-hour campaign to have the latter fact recognised by anyone in the medical profession, however, I eventually managed to get an alternative script, and the pain is now under some sort of control. It was touch and go for a while, but I've had 24 hours now to get used to the new regime and I think I've got my schedule optimised.
Which means I can go to Hi-Ex after all!
Offline now till Monday.
