I slept for about 7 hours (which is far more than I've managed most nights this week), and then crashed for a couple of hours this afternoon, too. Which is good, but I sort of object to losing my own time to sleep rather than work's time, given they've been causing the insomnia through bad management-induced stress.
Not that falling asleep at your desk is looked on as a good thing. Colleague now has a CPAP thing though, so it hasn't happened for ages.
