Bite Off More than One Can Chew

I'm having a great deal of difficulty with this 10pm to 6am schedule. I find that it's harder to concentrate on little things that I badly need to do...LIKE STUDY FOR THE BIG ONE!!! It's just been a little over a week since I got the night shift but it feels like ages. I'm irritable and I feel like sleeping all the time. I'm sleepy when I'm awake but I'm half awake when I'm supposed to be sleeping. Man, I'm really starting to think that scheduling The Big One this May was a huge mistake. With the rate things are going, I won't be able to comfortably cover all the topics that I need to read with the time I have left. GGGGGGGGGGGGRRRRRRRRRRRRRRRRRRRRR!!!!
