i am going in tuesday for an ultrasound of my liver and gall bladder. they are talking surgery, which i would rather not do. i have been reading about the flush and want to try it but have some concerns since i really don't know what to expect. is it dangerous? painful? is it hard on your system to pass the stones? i guess i am responding to you because you were kind enough to share your past experiences and i was hoping you could give a little more info on your first flush. thank you....
