I've tried something similar although a much smaller step - I've tried to go off for 2 days at a time - but then I'm always afraid I've missed some piece of fiction that I'll never find again. Consequently I stay up until 1 or 2 in the morning trying to catch up and end up going to work late!

good luck and I'll be waiting for the wonderful fic that is going to come to be because of your plan.
