I used to work graveyard, from 11pm to 7am or midnight to 8am. Mostly as an CNA but before that as a factory plastics molder and later at a live in school. I loved graveyard cause I never slept anyway. And it's great for getting to work when all the cars are going the opposite direction. But yeah it was a bit of a hassle before I had transportation cause yeah, busses don't run late. I wanted to sleep from 9-5 but that's when all the appointments are so my sleep was erratic and did me no favors for my bipolar.
