Can't Stay Awake

Today was just a struggle.  Maybe the 5 hours some sleep last night wasn't enough because I was struggling to get through my math today.  I couldn't keep my eyes open and couldn't concentrate on the problem.  I had a silent prayer a bit ago and that seemed to have made the difference.  Well, that along with some ice cream that I awarded myself a spoonful or two of every time I got through a question.  I was able to focus and suddenly the I was able to concentrate, understand what the problem was asking and then complete it.  Struggle.  Now I seem to be wide awake but need to go fall asleep.  I'm sure I'll be able to manage it once I lay down. There's only a couple time when not being able to stay awake is a problem; when I'm driving and when I'm trying to do homework.  Well, there is also the reading and I have drifted off in conversation, then there is the occasional movie in the theater and more frequently at home - especially if I have seen it before, I've also managed to fall asleep whilst typing this blog/journal.  I can successfully sleep on a bench in Disneyland and really have no trouble sleeping on airplanes.  I can sleep while standing in line but that can get embarrassing.  I do enjoy a good power nap.  Well, I think I shall quit now before I begin the drift.
