Thanks, Rob. I need to change my diet. Period. Not just for stones. My brother-in-law just found out he has 2 large stones and they are going to do a surgical procedure where they go through his back. It was never needed on mt because my stones were smaller. I do not know yet what his stones are made of. His daughter is a doctor and she has not given him any advice. Probably had little education about diet as you said :-)
