Ideas or recommendations to help avoid further kidney stones? i've had them just once, but dont want them ever again lol

The usual advice: First and foremost is drinking plenty of water. Never allow yourself to pass dark yellow urine. Get checked for a parathyroid adenoma. If the stones are uric acid or cysteine, or triple phosphate / struvite, a specific Rx is probably in order.

Diet and fluid: Calcium oxalate is most common in adults; reasons: dehydration; excess calcium in urine; excess oxalate in urine; low citrate in urine. Diet: avoid spinach, rhubarb, strawberries, nuts, chocolate, tea, wheat bran, and dry beans; drink OJ 8 oz 2x daily; add ReaLemon extract: 4 tblspns / day; increase fluid 4 liters/day; only 4 oz meat/day; low salt; 4-5 fruits/day;
