My stone is 2.8 cm and at this point I don't know if it still there. I have been flushing for more than 2 years and feel fine. You can check my old messages and see if there is more info there. Just click on all hanna's messages next to my name.
You can live with Gallstones as long you keep your liver clean. Also a better diet will help so you don't get new ones. Though I would think as long as you keep flushing your liver most stones won';t make it to your gallbladder.
I have a doctor's appointment this month and I am planning to ask him for an US.
A year after the flushing the stone was still there.
