I've become a night worker. To put it mildly, it's become mildly annoying. I start studying/writing code at night and before I know it, it's morning. I can't seem to stop. I then end up feeling weak and sleepy during the day when I need to be awake. If I'm lucky, I get a few hours of sleep during the day. And then at night, it happens all over again. I need to fix this.
