My brain collapses into mush around 5am. It's mostly pointless my staying awake past 4--I spend more time trying to keep my eyes open and trying to make sense of the words in front of me than I do fixing bad writing. It also sets me up to miss most of the next day, which is not good.
Nearly at the end now. I'll be so glad to have this over. If I've been ignoring your email, I apologize--my INBOX is nearly at 500, and every message is one I have to respond to.
