If you want to write and have a finished book to show for it this is my advice: don't stop!
I recently took a month off and this month ended up being six weeks long. After writing daily since November 1st I was in danger of burn out. In two months I had written one and a half novels and needed a break. January came and I had a delightful time not writing. I didn't feel tied to the laptop, I didn't feel guilty if I spent my spare time doing something other than writing. When February came I just couldn't get back into it. Nothing motivated me to finish my novel. Then I made myself start and it wasn't very good - I'm sure the resulting chapter is one I will have to go back and polish another time. I couldn't remember what had already happened and who was called what. I couldn't remember who put cookies in Tupperware and who used tins.
Last night I stopped writing and re-read the book so far, editing out errors as I found them. I corrected the Tupperware for tins and checked I hadn't already given Colin Maitland another name. I was relieved, as well, that it wasn't too shoddy.
So my advice to you is to write everyday until the work is done. This is the advice I shall be following myself in future and maybe my breaks will be between novels, not in the middle of them.
