I had short nap earlier today, but now I miss another nap. Fact is that I'm not tired at all. That's because of earlier oversleep. I mean, you could practically handle one day with only four hours sleep without naps, it isn't a miracle that I don't feel like sleeping. Even two hours would be too much.
That's why I'm still at the starting point when it comes to adaptating. I simply have to stop oversleeping. I figure putting my phone into hard-to-open cardboard box would force me to wake up to shut it down. We'll see. I'll start using it tonight, but not yet on the next two naps. I'm confident I don't have any problem with those.
