Pat,
There are some discussion forums/groups on gallbladders/gallstones that you might find helpful. There is one on yahoo.com that requires membership in order to read and/or share.
Although I had no indication for doing so, I underwent some natural therapies for eliminating gallstones. I lost about 7 pounds and there was stuff that came out that, to this day I have no idea what it may have been. I completed the process 3 times and each time seemed to eliminate larger although fewer 'stones' than the previous attempt. Again, I had no problems with my gallbladder nor with the passage of stones through the ducts so my experience will not be helpful to you.
I am providing the following link for information/amusement. There are quite a few pictures on the site including some of an actual gallbladder surgery. There are also links to discussion boards. I am not affiliated in any way with this site.
