Well, I wouldn't do it if it meant that you worked seven days straight without time off, year after year. How about being ill and unable to work, who will step in? It gets pretty draining. I know firsthand. Did it for ten years. you'll meet a lot of interesting people but it is the rare one that will care if you are there or not, any bloak would do. Try to change where you are in your present career. Can you move your location? What could you do to infuse your workday with a fresh outlook? Whatever you do, I wish you luck.
