+The end of week five on my [sleep schedule][schedule] marks the completion of
+one month on the schedule and one week with only a single minor sleep in.
+
+[schedule]: /personal/2011/01/polyphasic-sleep-schedule/
+
+The fourth week was much like those prior to it. On schedule for a while then
+a big sleep in. [Matt] suggested that it was time to make a change otherwise
+this pattern would continue forever. The proposed solution was a second alarm
+device out of reach, thus forcing me to get up. This had the added
+psychological hack of not wanting to disturb Amanda and therefore providing
+more motivation to get up and stop the second alarm before it goes off.

+
+As mentioned earlier the out-of-reach alarm has been a success. I've been up
+at 2am everyday since I started using it. The only sleep-in encountered since
+adding the second alarm was after my first morning nap one day. I now use the
+out-of-reach alarm for that nap as well.
+
+I certainly feel like I'm adapting to the schedule. The last two days haven't
+taken long at all to shake off the tiredness at 2am. During the day I'm
+usually only tired as a nap approaches. There are still some extreme tired
+moments though. The train continues to see me fighting to stay awake,
+particularly the morning trip. In general my body feels physically tired. Its
+one thing to be able to stay awake and be functional at work but another to
+feel energetic riding my bike to the station.
+
+Around the middle of this week I was very close to giving up the schedule.
+Partially because of how I felt and also because of a planned night out on
+Sat, in which my core sleep was right in the middle. Working the schedule
+around late nights or the odd party is going to be one of the trickiest
+things. This particular night has been cancelled so I'm remaining on the
+schedule for now. I hope to see further improvements in tiredness and energy
+levels in the coming week. Having been in a state of tiredness for the past
+month there are times when I just want to have a nice long sleep and feel
+fully normal again. However then I think about the huge amount of extra time
+I'm getting and don't feel like giving that up.
+
+The aim for the coming week is to continue to stay on-schedule and to
+hopefully see further improvements to my adaptation.
