I did this at the start of 2014 last year, and I have to say whilst it was the best choice I made in my life that kick started me being productive it wasn't the most smartest thing to do with nothing lined up on the short-term.
From a financial point of view it was a stupid decision even if I had money saved up but from a health and mental well-being it was the best thing to do. I think you have to weigh up your consequences really.
It took me about 6 months to find a proper job (office based and not retail but not bashing retail!) after quitting so that;s something to bear in mind; and honestly, after a week or two off you'll start to get extremely bored and ponder what you're going to do with life!
Wish you all the best with your decision but don't rush it!
