I'm having to write up as I continue to collect data and it's horrible - so I know where you're coming from :-( You've got the data though, and you'll know your research better than anyone -so it's just planning a systematic approach to each and every chapter and what you've got to say in them (which might sound like I'm stating the obvious :$ I'm health and a tiny bit social sciences with my research, so unless your research is something similar, I can't be that much help.
By tomorrow though, I'm certain that there'll be a lot of helpful advice for you though.
