Please refer to www.liverdoctor.com for great diagrams on the liver and gallbladder, and how the stones make it down and out thru your colon. :)
Since you have no gb, your liver is constantly dripping bile salts. This can cause irritation and diarrhea. :(
just in case the pain you are feeling is irritation/inflammation, try drinking ginger tea, eating fresh ginger, and taking ginger herbal pills. Ginger is an excellent anti-inflammatory.
You may still have stones in your liver, so flushes are still a very good thing to do for your health! :) Just change the recipe to a lighter dosage of juice, as the juice is there to contract the gallbladder. You still need some juice to emulsify the oil.
You might want to try Gold Coin Grass or chinese Bitters from www.sensiblehealth.com. The first will dissolve stones in your liver's bile ducts, the second will help your liver detox and grow stronger.
