I scored an 11. I know I am somewhat sleep deprived during the week when I am working a 3 day stretch, because I have a 1.5 hr. commute one way. By the time I get home, I have only 8 hours before I have to start back to work. When you factor in time to shower, dress, and makeup, etc. that depletes my sleeping time even more. So I get 5-6 hours of sleep between shifts. With the shifts being 12 hours long...I am totally exhausted at the end of the last day.
