Hi Pat, the calcified stones are the only ones that show up on Ultrasound. Did they say how big they are? (My biggest is about 1 cm). It will take you probably a few flushes to get those ones out. (According to Dusan, the gallbladder gets stronger with each flush). In the meantime take the stonebreaker to try and break them down.
I've been taking 2 TBSPNS olive oil mixed with water and 2 TBSPNS lemon juice every morning. I also add ginger which makes it yummy. Olive-Oil is good for you so yes, take it! Or you can just do this in the week leading up to the flush. A lot of practitioners say it makes for a more successful flush. It's also good to juice a litre of fresh apple juice a day (preferably green apples as they have more malic acid) in the week leading up to the flush.
Tell your wife not to worry. Literally thousands have done this flush and it's VERY rare to have a problem.
