>>10865531I dunno, man. I've been nocturnal for as long as I can remember. I get wide the fuck awake around 8pm regardless of how tired I was all day. Daytime just makes me tired and I feel like complete shit, like my energy is drained. Doesn't even matter if I fix my sleep schedule. I can go for months waking up at 7-8am, bed by 11-12. But then it always gradually shifts to a nocturnal cycle. I personally believe some people have natural nocturnal cycles.
