Well that wasn't part of the plan. Full on migraine today with all the extras (although heart fine). Never a good time, but work very understandingly reorganised some meetings into next week.
Spent the morning sleeping as much as possible, and started to feel a little more human this afternoon. Ended up finishing off Jimmy Carr's book, which was a worthwhile read.
Hopefully fine for a return to active duty tomorrow - particularly as one of my tasks is going out for lunch!
