To sleep or not to sleep

It's only 9:30pm but I am already very tired from working overtime this weekend. And I'm not yet done with all that paperwork due tomorrow!

I now have to make a decision: I may either continue drudging on in my groggy state and risk making mistakes--as past experience has taught me--or else hit the sack early and just wake up early tomorrow morning and resume work. Hopefully I'll be more wide awake then and be less prone to errors and get more work done at the same time.
