When you've got creative momentum, the last thing you want to do is stop. I'd write and write and wake up with my head slumped over and my fingers still on the keyboard and the last sentence trailing off like eeeeeejjjjjjjjjjjjj . . . Then I'd finally crawl to bed. Mornings were rough, but I got used to it. It was invigorating to write a couple thousand words while the rest of the world was asleep. More invigorating than rest.
