OMG Wendy! You have literally outlined what I do / used to do when at home!!!! Except that since I don't have any deadline of any sort, I tend to wile away more hours at the comp in the name of research!!!! And I hate it :( My DH is understanding, but.......why can't I be serious and write for a set time daily? !!!
Good luck with having the book raring to go before the deadline!
