I agree with the others you should take a few days minimum off to rest an recuperate. I would rather you rest an get back into the story rather than burn yourself out. You are writing a great story so I would totally rather you keep with the quality rather than quantity. Also if you get burnt out you might wrap up some things sooner or do a poorer job on them to rush through. Which is counter productive to a good story like you are doing so far. Plus a small break will give you time to relax and thing about the story and ideas for it without feeling pressured.
