I did it. I wrote my last two chapters in 2 weeks. I analyzed the data and wrote the last one in 8 days. I just sent the whole formatted shebang to my committee, 3 weeks before the defense. More than 200 pages, i to vitae. I cried after I sent it. In fact, I sobbed. I did it.
Turns out I'm exhausted. I've got plenty of half-formed blog entries in my head and I look forward to getting them out over the next few weeks as I resume something like a normal schedule and catching up on all the life things that I've been putting off for weeks and months to finish my dissertation by today.
