Once the pressure was off with the book, I collapsed in a bit of a heap. Since August, I've had two days off sick, but apart from that, the only day I haven't worked on the book was Christmas day, and I was cooking for a good bit of that.
And for the last week, I've been ignoring the housework almost completely.
So Tuesday afternoon and Wednesday were spent catching up on sleep, taking the Christmas decorations down, and scrubbing the kitchen. Today, I'll get back to work on the book, because it still needs finishing.
