So tired... so, so tired

Um yeah, we all know that I have sleeping issues. Problem is that I had all last week off of work and completely got my days and nights turned around so that I was staying up until 8 or 9 (or 10) in the morning and sleeping til 4 or 5 (or 6) at night. Now I have to go back to work tomorrow so I decided to stay up all last night and today and just go to bed early tonight to get back on schedule. I don't know if I'm going to make it. It's only 9:30. Holy Crap I'm tired...
