I may be have been the only one with a 1" gallstone that has done 80+ flushes over 8 years, used every supplement for many months,which were mentioned on the Liver-Flush support forum.
My result: it changed my life got rid off lifelong allergies, 40 years of prescription drugs (amphetamine, prozac, zoloft etc).
Started flushing since I "needed" surgery, stone stuck in gallbladder neck, inflammation, thickened wall. After 10 months all these symptons were gone and the stone free floating. At this point I feel well but still have my stone.

Stopped flushing about 2-3 years ago after reading the following.

Check under Modern Chinese treatments for gallstones.
They do flushes in the hospital for many days and often use epidurals and they found they could do it with stones up to 1 cm.

Over the years I never got out many stones and often none, but as long as I saw bile I knew it had cleaned my liver and always got rid off my brainfog.

So I am not here to discuss what the stones consist of or how big a stone can come out, just that cleaning the liver can do wonders, at least for me.
