I was first diagnosed about 7 years ago. Only the calcium ones show up in ultrasound so I've got them too. I did 2 slow method 2 cup flushes 3 months apart. Have described before so won't go into detail but radical change to my health. My GB had been totally blocked. Well subsequent x-rays showed same bunch of stones so I was very disheartened. I didn't know then about calcium stones versus bile stones showing up differently. A year later I did 1 litre of fresh juiced apple juice a day for 7 days then drank a cup of grapefruit juice mixed with a cup of oil. Got out some quite big stones that looked very different to the ones I had flushed out the year before. They were large and pale and kind of powdery surface rather than emerald green. Now I know they were probably old stones. But I had heard the olive oil turning into stones idea and lost heart.
A few years later came across Hulda Clark 's book - revelation!! I flushed her way a couple of times then got really busy with studies and let a few more years go by. Then 2 years ago my GB began to trouble me again. So this time round I've done 2 successful flushes (Clark way) and 1 unsuccessful (last weekend, slow method).
Sorry for the long story but that's my history!! Much as I would love to do the 2 cups way, I guess the gradual process of Clark's way is best for me now.
