(3:11 hours)

I think that has to be about the worst night's sleep I've had since I started sleeping biphasically!

After about an hour awake in the middle of the night I laid down on the floor to test how sleepy I was (I didn't want to disturb Yu Lee going in and out) and I realised I would probably sleep if I went back to bed. When I got back in bed I fell asleep straight away but I think I woke up at 3:30, and then 4:30, so when I woke up again at 5:30 I thought it was definitely time to get up.

I feel like I could go to sleep now. I feel like I could probably sleep forever like that, as the quality of my sleep was so poor that I would probably never stop being tired enough to sleep!

We have recently got our house insulated, and the temperature inside is a little higher than it used to be. I wonder if the new temperature is what was stopping me from sleeping properly...
