Merry Christmas everyone! Celebrating the best news that came in the smallest package, Jesus entering the world so that God might dwell among men.

Today went according to plan! I was able to sleep at home for my daytime naps, which made it easy to fall asleep. I also took my first nap in this experiment on the train tonight. In all my sleeps, I was able to go to sleep, then wake up when I was supposed to, and not oversleep, while still functioning fine throughout the day. After my incident with oversleeping yesterday, today I took extra care in not delaying getting out of bed when my alarm went off. It turned out well.

My midnight nap returned to a quality similar to the first day, and I woke up feeling refreshed and awake. I managed to stay awake till my scheduled 4am nap, feeling only a little drowsy. This time, instead of having only one dim light during my awake time, to simulate daytime and to avoid falling asleep, I turned the main room lights on and kept them on till I went to bed again. I spent the time making some travel plans in the upcoming few days spent at my dad's place. I didn't eat anything between my midnight nap and my 4am nap this time.

Up until my 8am nap, I caught up on some email, watched some TV, and did some light aerobic exercises to pass the time. I spent the daytime reading, writing emails and watching TV. For breakfast I had yoghurt and cereal, and for lunch I ate some bread and rice with stew.

The whole morning, I suffered fog of brain which led to slightly slurred speech, but my bladder control and appetite were both functioning normally. Another sensation I thought I'd mention is that I feel quite cold even indoors. I don't know if it's because it's currently winter, or because I'm having issues with thermostatic homeostasis, or both, or something else altogether, but maybe I'll be able to interpret the sensation better as time goes on.

After my 4pm nap, we set out for Ginza for a dinner my dad had booked from a while back. It would have been nice to have been attend the Christmas Eve service at church, but my dad had booked already before I'd shared that idea, and it's kind of difficult changing reservations around this time of year. Well, I have this Sunday to visit the church I was planning on going to. In the meantime, the dinner itself was amazing. It was a Japanese style meal that came in several courses (lost count) and it was themed around fish and seafood. We had sashimi, fish head miso soup, grilled fish, scallops, and rice cake dessert with abalone, amongst many other dishes. Probably not the best idea to eat such extravagance when I'm adjusting to a brand new sleep regime, but it was an experience worth every bite.

In hindsight, we all regretted not dressing up more formally for today :P


In the end, I was still able to sleep reasonably soundly so that was a relief. The only issue was, the dinner finished at 7:40 and it would be awkward to pass out at the dinner table so I had to either delay my sleep till I got back home, or sleep on the train. It just so happened that at 7:58pm, we transferred to a train that we rode to the terminal station, and the trip was exactly 29 minutes, and I managed to get a seat. So I took my nap on the train. I recollect hearing the announcement for the first stop after I'd prepared to take my nap, but nothing else after that till the train pulled up at the terminal stop, which suggests I managed to get at least some shut eye. I consider that pretty impressive, since I have never been in the habit of napping before commencing this sleep experiment. Even if I terminate this sleep experiment for whatever reason, I am still glad to have gained insight into the art of taking short naps.
