For prep, I missed sleep and endured complaints. LOL It's definitely not easy, but it's doable...at least, for me. I'll also be traveling during NaNo, though not as much as you. I'm moving in November 2 and don't even get there until the 4th. I'll probably write on the plane. For prep, I sometimes wrote on a bus ride. Lol

Don't question if you should try. Of course, you should! There's no penalty for trying, even if you fail. Say you only write 10k words. It's 10k more than you had before.

Go for it!! I believe in you! Good luck!
