Gallstones

Hello. I am a 38y.o female and have suffered with multiple gallstone attacks that vary in duration from 30min to 12 hrs. I am hoping to be recommended a remedy that will help desolve my stones as I really do not wish to have my gallbladder removed. Ultrasounds have shown I have lots of small stones approximately half a centimeter in size. My weight loss is what I believe has triggered these attacks even though I still haven't reached my goal weight and am still overweight.
When I have attacks, they begin as a pain in my stomach with tenderness over the gallbladder area on the right of my ribs. When it's a mild attack, it remains at that and feels more like an acidic/cramping stomach. When the attacks are severe, it starts out as explained before and keeps building up slowly to a stitching pain over my gallbladder, severe pain in my stomach and severe pain in my breast bone. This is usually accompanied by flatulence and belching and most times passing of stool which is formed and normal in colour (brown). At this point I can't get any relief no matter what position I put myself in and my clothes feel tight and bother me. With the use of the Remedy Finder I have found Pulstatilla, Nux Vomica, and Berberris to be of help depending on what stage my attack is in and how sever it is. But ideally I would like something to help desolve the stones so I don't get any attacks. I also have a cholesterol level of 6.1
I hope I have provided enough information. Please let me know if you require any further information.
Your help is much appreciated!
Thank you in advance
