It's not really that late, only 10:30, but I'm aggravated that I am awake even though Dan is snoring blissfully in our bedroom. On a happy note, Dan has indeed come back from his many world travels, and I am so happy. But back to whining. I am desperately tired and I cannot go to sleep. I have a hard time winding down at the end of weeks like the one I've just had. It's been very full and very stressful and even though it's over now and no new deadlines are coming my way until Monday, I just can't let it go. I am re-running conversations I had this week in my mind, mentally reciting every word I have written for tomorrow's paper, and feeling my shoulders get more and more tense instead of relaxing into the sleep that I need so much right now. It's amazing that your mind is capable of keeping your body awake even when all you need physically is to sleep. I'm sure this serves many purposes, such as keeping us from falling asleep at dangerous times, but sometimes I wish there was an 'overide' button on the system. For now, it seems that David Letterman and I will be spending the evening together. I am optimistic that this will put me to sleep.
