But, don't think you can stop and not have any more stones. You will probably need to flush many, many times before all stones are gone.
It's kinda like losing 5 pounds, but you know you need to lose 30. Do you stop at 5? No! Sure you will reap benefits from just losing those 5 pounds, but think how much better you will feel when you lose all the weight you need to lose? The same is true with your stones.
