Have you read the Liver Cleansing Diet by Dr. Sandra Cabot? I recommend this book highly, especially if you are considering doing fasts and cleansing. It's a way of cleaning out your liver without starving to death. And it is very helpful.
I'm currently trying to avoid surgery, though it's not gallbladder. I'm following this diet, except I'm avoiding all fat for the time being. My problem is the common bile duct and the pancreatic duct are very tight and don't open properly. They've never found gallstones, so I still have my gallbladder. But I have gallbladder like pain, and I've actually had pancreatitis twice so far because the pancreatic duct has been blocked (maybe by a passing gallstone, no one knows).
Anyway, I really recommend this book, and it's a great diet for people who have liver problems. You can get it on her website http://www.liverdoctor.com
. I have no financial gain from this website. :)
