I know this is an old message, but I'll answer it anyway. When I had my gallbladder and had attacks, I usually had the opposite problem. One thing that I found to help me was drinking some Epsom Salts and sometimes it would stop my attack, that is, until the last few months that I had my GB and was having horrible attacks. But I usually didn't have diarrhea when I had an attack, I just usually had the opposite problem. Of course, the magnesium sulfate really solved the constipation.
