Shut up, Brain! >:( (aka I can't write because I want to WRITE, wth.)

I'm guessing quite a few other people here have had this problem, and I wish I was offering a solution instead of asking if anyone else has one.

I've gotten *really* into my current writing project. So much so that I think of one scene/sentence/something before I can finish the last.

Problem is... they're not concurrent. I might be writing a line in chapter 9 and get a *brilliant* idea for chapter 22. If I stop writing the chapter 9 line, I lose my train of thought for the chapter 9 scene. But at least I have a scene for chapter 22, right? NOPE!

As I'm writing that, I get an idea for chapter 13.. and the cycle just continues. And of course, if I *don't* note my flash of inspiration, I lose it.

Normally I'd kill for flashes of inspiration, but having them so quickly together is almost worse than not having them at all! Ahhhh!

So... anyone have ways they deal with this? :P
