coffee thought...

it is 6:29 pm and i am soo tired yet i cannot go to sleep right. Why? Because right now is kind of like the witching hour where 2 things can happen if i take a nap now. Since i have to get up early for work tomorrow if i do decide to sleep now this would prohibit me from getting a good nights rest. If i struggle to stay up then i will just be more tired. What's a girl to do?
