Depends on the shift i'm working;
Day- I start at 7:00 AM, so I get up at 6:00 AM, and finish my shift at 3:30 PM
Afternoon- I start at 3:30 PM, so I get up at 11:00 AM, and finish my shift at midnight
Graveyard- I start at midnight, so I get up at 5:30 PM, finish at 7:00 AM
I cycle every two weeks for my job, so my sleep pattern is changed all the time.
However, I get up early on weekends (Depending on whether or not i'm hung over).
