I too still experience the pain even after three successful cleanses. Frustrated with not knowing how many more cleanses to do for myself until the pain stops, I have found some herbs that I am going to take to increase the successfullness of my cleanses. I can't even take flax seed oil yet because it causes me gallbladder pain or attack.
Go to the website, www.sensiblehealth.com. I am going to try the Gold Coin Grass Tincture. It dissolves gallstones, to be used before a cleanse. They say within days of taking this, the gallbladder pain usually goes away. I am also looking into peppermint oil. The menthol in it helps to prevent and dissolve gallstones. Listed on the website, there are other herbs to help the liver and gallbladder produce or release more bile to make the cleanse more successful too.
I've just had to change my attitude and be more patient, realizing this may take a lot more cleanses than I thought.
