Have you ever tried liverflushing, see support forum. Cleanses are at top of forum.
Dr.Sutter's forum has a flush without Epsom Salts .
I love Epsom Salts and do well with it, for 10 years I have had a 1" stone and when it acts up I use 1 tbs ES in water. You can also try a pinch several times a day.
You can also check the Truth in Medicine forum and use the grape bitters on the back of your tongue before meals.
You can check on any of he forums mentioned.
BTW when I started fushing in 2003 the stone was stuck in the gallbladderneck, there was inflammation and the wall was thickened. A follow up US after 10 months had the stone free floating, inflammation gone and the wall back to normal.
