I will tell you from my experience that I tried everything under the sun from remedies to drinking recommendations from others. Nothing worked and in the end I had my gallbladder removed in December. But don't let that discourage you if you don't want the surgery, what didn't work for me might work for you.
If you have tried everything and the pain is keeping you awake or prevents you from functioning like it did me then you might need to look into the surgery option. I can say this, since it was removed I have been able to go back to the life I had before the attacks started happening 3 years ago. My gallbladder was full of stones which I passed and they came back over and over again.
I also did the Liver-Flush after I went to the ER 3 years ago and was told it was all in my head and it wasn't my gallbladder by the doctor there (he recommended the LF, believe it or not). I know my body though and after the Liver-Flush I had stones removed. But they came back and after 2 and a half years of trying to fix the problem was when I had the surgery.
