Why am I awake?

I have been up for almost a straight 24 hours and am getting ready to head into work for a grueling 8 1/2 hour shift. I generally take a nap in the morning after I send the husband off to school around 4:30 a.m. CST and then again after the boys get on the bus around 8:30 a.m. CST. As it is, this morning I wasn't able to get myself to fall asleep during either of those time so here I am (mostly) wide awake and getting ready to head to work. I have a feeling this may end badly, but I also know I don't have a choice. I work for a place that carries a "no fault" attendance policy. So, leaving early would only give me points and after a certain amount of points you have to pray that someone will have mercy on you and not fire you, per policy. I have been extremely fortunate up to this point that my direct supervisor is amazing and awesome and wonderful and she has forgiven many of my points - because I had doctor notices for illness primarily. However, I don't have any points to spare so I am stuck at work through the duration and I will be doing so on little to no sleep. Yay me /sarcasm. Wish me luck as I have a feeling I'm going to need all I can get.
