I once had a "staghorn," which is a kidney stone so large it takes the shape of the entire inside of your kidney. It caused sepsis and I literally almost died. I went into shock before they could start going to work on me.
I actually don't drink anything other than water and sparkling water, but at the time I drank a lot of milk and soda. Even though I've only had water for two years I've still had some small stones, apparently I'm genetically predisposed to them
