I hear you Jester. I had a bout of it over the weekend. I just couldn't sleep Friday through Sunday. It finally caught up with me on Monday and I fell asleep at 8:00pm with my daughter and slept all not long!
It's just because you have some much going on right now but hopefully things will settle into place and you'll feel better. Besides, going into the Army you better try to enjoy all the sleep you can get now because you won't be getting very much when you get there!!
