I'm a 51 year old woman who has recently had quite a "bout" with kidney stones. I've never had any trouble in my life with this before....so after getting MRI and CT Scan and seeing doctors and uriologist....and not getting a whole lot of help, just lots of BILLS....I sat down and tried to think of what I was doing differently in my life now, than before....the only thing I could come up with is that I do use a lot of "Splenda"...I think I'm addicted to it and I used to use more and more....the doctors never said anything about it....I'm just "guessing" myself....I quit the Splenda now, and so far, I've had no more troubles....not sure if this is WHY or if this was just a freaky coincidence, nevertheless, wanted to pass the information along, maybe it could help someone else.
