You need fat!

You MUST try to give your body fat. I know you're saying it makes you ill. But at least try 1 tablespoon of olive oil with 1 tablespoon of lemon juice every morning. Low fat diets cause Gallstones too (that is how I caused mine).

Have you had an ultrasound or anything? I think it would be good to know what shape/size your stones are and what condition your gallbladder is in so that you know what you are up against. (maybe you've already had this checked out).

How about some kind of gallbladder herbs. Seems the best are from sensible health.

If you are only eating raw fruit and veggies, you are going to cause yourself more serious problems in the long run.

Look into digestive enzymes (Biogest is said to be good) and probiotics (Primal Defense, Flora balance are two that people recommend). Kefir is good too.
