I have to admit, I'm wondering if in my case it might be partly the anti-depressants. I am a LOT happier and calmer at the moment (I've had two weeks of actually enjoying my days off with Jack and almost looking forward to them) - but calm and happy does not tend to make for good writing. Or even any desire to write.

Congratulations on your bigbang, though. 6k is very impressive! :-)
