My work schedule rotates. It's a fireman schedule 4-12hr shifts then 4 days off unless I work OT. So if i gotta work days then somewhere around 930-11pm, get up at 5am. If i'm working overnight i usually sleep around 7-8am get up at like 2-3pm.
Im an vampire, night owl type dude normally, up all night sleep all day. Lack of food or sleep i'm cranky lol
