Just want to say that I relate to the fear issue--when I first started, I had very little info and I was afraid that a stone would get stuck and I'd land in the emergency room with all the doctors laughing at my home cure.
However, I'm on cleanse #10 and counting, have passed stones up to an inch long(!) and didn't even feel it happening. I hope that is reassuring. The oil/juice can be a bit grim, but nothing like a gallbladder attack.
It sounds like the pain you describe is definitely gall bladder related.
Grace to you as you and your husband embark on this journey!
