As with yesterday's post, I am writing this the day after in the morning. Yesterday would have been the 17th day of the biphasic experiment.

Yesterday was the second (and final) day of my course. The previous night I had crashed from about 8:15pm to 4:45am for a total of 8.5 hours, and although I had a lot of sleep, I actually think I felt worse yesterday!

I have been recording my alertness levels throughout the day, and I will post a chart at the end of the week, but my average score for yesterday was lower than the previous day and I also had this 'aching eyes' feeling all day.

Yu Lee sent me a text message during the day saying that she had napped from 9:00pm to 10:00pm, and then slept 4.5 hours from 1:00am to 5:30am, so she actually did my sleeping pattern better than I did!

When my course finished I came back to Yu Lee's mum's house, and she had already cooked dinner. After dinner I wanted to have a nap but I realised that I wasn't tired enough at that point, and after another hour Yu Lee had arrived to pick me up. We ended up leaving just before 9:00pm, so I didn't have time to nap before leaving. In the car I was extremely tired, so when we got home at 10:00pm I decided to set up my alarm and go straight to sleep.
