Gallbladder Attack Remedies

Have just read about lecithin helping gall-stones, and I have been taking lecithin in granules for about a year, mixed in foods, but am still getting gall-bladder attacks. I have five small stone in the gall-bladder and one stone blocking the bile-duct. I also take plenty of apple juice and other juices and also milk-thistle and aloe vera juice. As I am very ill and weak anyway with a muscle disease, I want to avoid surgery if at all possible. Can anyone suggest anything else to ease these attacks. I went about 6 months without any and they have all started again.
