Ah, see, that's perfectly understandable. Life has a tendency of getting in the way, and that does change the course of action needed for getting writing done. In your case, usually the best course is just set aside time for getting writing done, which is easier said than done at times. Have you tried changing what you use for writing, maybe a different sort of computer than what you use for work, or even so far as switching to pen/cil-and-paper? May not be doable or work at all, but it could be worth the attempt.
I have not tried that yet, but that could possibly help, at that point when I'm not as tired from sitting in front of a computer I can easily transfer it over. I should maybe try that, or at least jot down notes to make other chapters easier to breeze through at a later point. At work it is a bit hard, it is a call center so I am on the phone and on the computer all day other than my break times.
