My husband has problems in this area (he even has a few gall stones) and the best thing for him is to stay away from tomato base meals and sauces, avoid heavy meals (especially deep fried), drink milk in moderation and take his Prilosec Rx every day..... keeping tums on hand for those in between bouts help too.

Doctor told him he may need to have the gall bladder removed if the pain gets any worse or the stones grow.
