I'm a night owl. My body wants to go to sleep around 6am and wake up at like 2pm, and if it doesn't get to it will rebel. I used to struggle with resetting my sleep schedule all the time. Falling asleep during the day, gradually drifting later on my days off, and usually feeling kinda shit.
Went back to working nights, driving a cab 5p-12a or 3p-12a depending on the day. I love it. I feel so much better. My body is never easy, but it's a hell of a lot easier than it was. One less thing to worry about.
It is hard to make appointments, and companies are always trying to call my firmly muted phone at 9am when I tell them not to, but it's a lot more comfortable. I see all kinds of neat crepuscular animals and there's like no traffic.
I think it very much depends on your body's natural rhythm. People like to chalk it up to 'insomnia', but that's just pathologizing normal behavior. Nothing wrong with being nocturnal.
