Editing a novel for NaNoWriMo

Every year, I try to consider writing a novel for NaNo. Well, I already have my fantasy novel "Malrith's Shield" written. It took 3 months, give or take a few days/weeks, to jam out--which for me is damn good time. And it's my first real novel.

Now I'm at the major revision stage. *breathes*

Editing or revising, whatever you want to call it, always overwhelms the hell out of me. I can do simple revisions usually without any problems, but this novel needs A LOT of work! I don't write clean first...
