Writing frenzy

Yesterday was crazy! I wrote a brand new scene (4k pages) for a book which was just undergoing its final proofread, and then I had a new concept for a novella (spinning out of that scene), and before I knew what was happening, I had finished a first draft of said novella - 10k pages. It's true I didn't get to sleep till 6.30am - but still, that's a lot of writing for one 24 hour period. Looking forward to reviewing the novella when I'm feeling a bit fresher!
