I also can handle a lot of pain yet this gift was unecessary for my first flush completed yesterday, See aquarium gravel post.
I had several clumps of cholesterol come out the size of a kidney bean. Most were the size of aquarium gravel and raisins. I had no grapes, walnuts nor golf balls come out so I can only speculate that considering the action of magnesium in relaxation of tissue, action of olive oil mixture in lubricating and the follwing release of bile in expulsion I believe if you adequately prepare according to instruction here combined with each succeeding flush, over time your body will accomodate the release of the larger ones.
