I work at a McDonald's which is open 24 hours, and I am daytime staff as well as graveyard staff. my earliest shift starts at 6am and my latest shift starts at 10pm. I do graveyard once or twice a week too. is this going to affect my sleep and health? I woke up at 5am this morning and worked from 7 to 2, then got home and slept until 6pm. what do you think?
