As expected I became sleepy bunny by at 9 and gave up at 10. Staggered down the hill all bleary and half asleep. Walking places whilst asleep is a bit like being drunk. You can't focus, your feet barely walk in a straight line and you just want to curl up in a hedge somewhere and fall asleep.
I got home uneventfully and pretty much crashed out straight away. Except that the heat kept me in a half dozey state. Tried opening the window a bit, but I think the insects were lying in wait outside and a few of them made another attempt on me. So I ended up closing it again.
Feel more awake than yesterday though, so I guess the extra hours I spent not sleeping properly helped. Still want to curl up under my desk and snooze though.
