I skipped gallbladder surgery (days away) by doing cleanses. On my first I had 275 stones and felt great, my second 250 stones and felt like crap. A year later I did a cleanse with none but felt great and all my gallbladder symptoms went again. I'm not sure why, but even if no stones show I think it is helping. My sister had only a couple with her first cleanse but felt good. Every cleanse will leave you feeling different, some better some tired (for a few hours only), but I believe they all help.
I ate the day before, just no oil or high protein. Stopped eating at 1pm, stopped drinking (H20) at 3pm. Had 3/4 c applejuice w/1Tbsp epsom at 6 and 8pm. Had Fresh grapefruit juice (1/2 - 3/4c) w/ olive oil (1/2c) at 10, and my apple and epsom in the morning when I wake, but not before 6am. (usually 6 and 8am. It has always done something for me.
I'm proof they help, I was down to 98 lbs at 5'4", and sick as a dog. Over six months I passed 12-1500 stones. Many people have no shows for their first few cleanses, don't worry about it. They are probably compacted and moving a little each time. If your bowel cleared than they are not in it.
