So, the last novel I wrote I did in three months. (It was, I should point out, a rewrite.) I think I burned myself out some with that one. This time I'm not pushing for as many words a day. It's somewhat frustrating for me because I need to rewrite so much. I usually write about 2k words and then delete 1.5k of them. In the past I've met my 2k limit by making sure that at the end of my writing session that I have 2k more words than I started with.
Yesterday, while trying to do this I got really tired and slept a lot. Part of it is no doubt pregnancy exhaustion, but I'm also afraid of burning myself out again.
For the next week or so, though, I just plan to stick to writing 2k, even if I have to delete most of them. Progress will be slow, but I'm hoping I don't hit any brick walls!
