My sister-in-law was told by a few doctors that she should have her gall bladder out and immediately, but she was nursing and didn't want to quit so she quit eating fat until her son wasn't totally dependent on her and she did the gall bladder cleanse, DR. Clark's, except she did drink apple cider and apple cider vinegar the week before hand. She had a lot of stones come out and hasn't had a "rolling on the floor in pain" apisode since. Acctually once she quit eating the fat before she did the cleanse she quit having the intense pain attacks.
