Random Sleeping Patterns

Something that has really caught my attention is how random my sleep patterns are. Some nights I will sleep a solid 7 to 8 hours, other nights I wont get but 4 to 5 hours of sleep. One thing that does not change is how tired I feel even if I do get those few extra hours of sleep. This feeling made me think of  the sleep debt, the term we heard in last weeks video. I am constantly depriving myself of sleep and I cannot ever pay it back effectively. It all comes down to putting myself to sleep at a reasonable time. This has been difficult mostly because of the late hours I am forced to work. I am curious to see my if my sleeping patterns will effect my upcoming midterm grades.
