Go insomnia go! I'm so tired, but I can't seem to fall asleep. I've been in bed for nearly 3 hours, and I'm so restless now. I can't concentrate on anything, so it's not like I can read a book or do a crossword or something. I just have no energy left. Is it possible to not have enough strength to go to sleep? How dumb does that sound? I dunno, at 3 am when I'm this tired, anything sounds reasonable.
