Whilst I was doing the experiment, I kept a spreadsheet where I recorded how I felt each hour throughout the day. I rated my alertness on the following scale:

Score Meaning
0 I give up
1 Microsleeps. Feeling like falling asleep when doing physical activity such as walking.
2 I could sleep at my desk by accident whilst trying to type something if I'm not careful. Occasional microsleeps a possibility
3 Uncomfortable (extremely tired) / very sleepy. Even just sitting down is uncomfortable and/or I have to fight off sleep constantly
4 Very Tired – I could fall asleep in less than a minute. Programming is impossible or at least very difficult
5 Reading would make me fall asleep or feel really sleepy
6 I could read without sleeping but it would make me feel drowsy
7 Normal Monday afternoon after missing a few hours sleep on Sunday night
8 Slightly Tired (definitely don't feel like I could fall asleep). Normally I would feel like this at about 8:00pm – 9:00pm
9 Normal Awake
10 Better than normal
This is not very scientific - I literally just asked myself how I was feeling each hour and picked the item on the scale that best fitted how I felt at the time.

Unfortunately I didn't record this from the very start of the experiment which included some of the worst times for me.

The following is a table with my results. It may seem like the scores are not very low, but I think the worst you should ever feel on a normal day is about a 6. A feeling of 2 is extremely uncomfortable, and 1 is living hell if you feel like that for extended periods!

I have colour coded the table: Orange cells are periods just before a sleep, and yellow cells are periods just after a sleep.

You will notice that the last day in the chart shows the day where I made the crossover from everyman to biphasic. I will continue to chart my feelings until I am fully adapted to biphasic, so that we can compare how bad each adaptation felt.

Also, if you look carefully you can see 1 hour where I scored a 9. During the whole adaptation period I had 1 hour of feeling normal on day 8. That's why I gave up!
