abnormal galbladder

I have been diagnosed with having an abnormal galbladder not releasing enough bile into the small intestines.  This is causing nausia every day and sometimes very intense and is causing me to lose weight.  I am debating over surgery which my doctor said he thought i didn't need becuase there were no galstoness present unless the pain got to bad and then we would have surgery.  I am currenty taking prescription Zantac and Reglan and am taking a over the counter Fiber.  Do you think the galbladder cleanse would help or is there another alternative or prescription that would help before I decide to have surgery.
