Super easy, ene. Basically drink apple juice (to soften the gal stones) for 6 days and on the 6th day drink two glasses of epsom salt then drink a mix of some olive oil with grapefruit juice (which isn't as bad as it seems) That mixture should push all the gall stones out of the liver. Next day drink 2 glasses of epsom salt again and you should be pissing out the stones of your ass.
But if you are really interested you should check out the book

goddamn! you should check out the book too. Could have some very useful information for you. There's a special section for people who've had their gallbladder removed.
Wouldn't be a low fat / high carb diet better for you if you have had these problems in the past?
