When do you quit stocking up?

Question folks--if you have been working on a stock pile for a few months...when do you quit stocking and live off of it?

I'm by NO means an extreme couponer, but I have managed to stock up on house hold items and keep them on hand for when I need them. But I guess I don't know when you actually start living off of the stock pile?

Any thoughts on this? When is enough-enough? When do you quit stocking up and live off of what you have already?
