I am a stoner- or was- I was getting upwards of 60,stones a year and lots of “sand”. Imhave a couple,comditions that cause to stones 3asily if im not careful. I finally figured out that when I ate salty snacks like cheeze-its in any quantity, I woild get several stones soon after. It took awhile to figure out unfortunately. I quit sa.ty snacks (although table salt seems to be OK for so e reason, not sure why), and was put pn allopurinol, and haven’t had stones in a couple years now.
Resist foods with high oxalate content. (Celery and spinach prominent).
