Extended career breaks work magic for me too. I recently took six months away from work and it was sheer bliss. I was doing some techie stuff - but only things I really wanted to do and didn't force myself. I did a lot of sleeping, walking, eating good food and generally relaxing. Worked like a charm and I went back to work reinvigorated. I do think though if you are significantly burnt out then a year off might be necessary in order to fully recover.
