I worked night shift for 2.5 years (9:30pm-4:30am M-F) straight out of college. I'll never do it again.

I actually didn't mind being up and working late, I'm a night owl, it was everything else though. I think people look at the hours and go "well I'm up till 5am anyways", but it's not like you get home and fall asleep right away. You shower, eat, decompress, watch tv for a bit, it's usually 8am before you're actually falling asleep. Hungry after work? There's two places open 24 hours in town, get used to eating those a lot. You can make a meal at home, just be careful not to wake up your roommates. In fact just be careful of that in general.

Friends wanna do something on Friday night (or any night)? You either can't or have to call it quits early to leave for work. Drinking more than a beer is out. Friends want to do something Saturday at noon? You're either joining them late or you're a zombie all day. Everybody's going to that movie you wanna see, but it starts at 6 and is 2.5 hours, you're not gonna be able to make it. Got a girlfriend? She's gonna feel a little lonely, especially if she works an evening shifts at a restaurant or something. You're gonna be scrambling just to find hours to be together. Saturdays and Sundays you can kinda recover and live a normal life but you don't wanna get out of rhythm too much because you have to go back to work Monday night. You just feel so off from everyone else, like you're living in two separate worlds, it's a weird quasi-isolation. You're kinda depressed and in the winter you'll go days where you barely see the sun. I lived with my best friend and some days the only time I'd see him would be the 30 minutes after he'd get up to go to work and I would be going to bed. Your coworkers become your best friends because they're the only ones who really get it, which has its benefits if you work with cool people, but for me personally I kinda wanted to have a separate work and leisure life.

Some people enjoy it. Some people look at all the stuff I laid out and go "oh well that doesn't really apply to me. I don't have roommates or a gf, I don't go out with friends and like being alone, I never see the sun much anyways", etc etc, then maybe it's for you. There are some positives. Driving is incredible. There's a serenity to nobody on the road and it cuts your commute in half. Summer heat? Literally never have to deal with it.

And at the end of it all, I made it through and look back and laugh. But I'm not doing it again.
