Haven't been updating my log for quite a few days. Work has finally caught up to me and I had to finish it before the deadline.

After the pathetic failure during the weekend, I am trying to shift my core sleep to as early as possible. Ideally I'll move it to 5 p.m. so that I can go work out in the gym. And even if I turn out to be too sleepy to do anything, I have the whole night to recover or crash, rather than risk a day at work.

---

10:16 p.m. -- 3:00 a.m. Core sleep
5:00 a.m. -- 5:30 a.m. Nap
9:00 a.m. -- 9:30 a.m. Nap
1:10 p.m. -- 1:40 p.m. Nap

I have been trying to go pure polyphasic for the last several days. But this has been proved to be very hard. Everytime around 3 a.m. to 5 a.m., I would be so sleepy that I would crash. I tried to play some game during those hours and I'd close my eyes when the movie is playing and fell right into sleep.

Maybe a good way should be move my core sleep hours to the daytime and try to walk around.
