The above phrase is always how I think of what life is like after NaNo is over. Even if you don't make it to 50k, your imagination usually feels like some kind of post-apocalyptic wasteland after all the work done. At least mine always does.
Here we are! We've finished the first week of NaNo! Doing NaNoWriMo can be a nearly all-consuming endeavor, but it can get overruled if you're also working or in school while doing it. Personally, I'm a teacher, as well as a house-wife, so finding time to work on my novel in between my other obligations can be hectic.
