Let me try to answer you. I have been here since 2003 and have done more than 60+ flushes. Since my stone is 2.8
cm what you have is small to me.
I have still my stone but my health has improved, of course I also have improved my eating habits etc.
I have done a lot of reading and based on a study in China stones smaller than 1
cm might come out.
I have read also a lot of people that had bigger stones but noone had ever checked if it was a calcified stone.
Since I am against anesthesia I never wanted surgery, actually I am more scared of that. May be if I could have gotten an epidural might have considered surgery, on the other hand I don't really have problems.
Search under the name Fernando, he started somewhere in my time and he had many stones, like you, but never had surgery either.
So I would suggest based on my personal experience and reading to do the flushes. Also you can check the Truth on Medicine forum. This forum is not for flushing but you could add that system to the flushing and see what happens.
Surgery gives other problems and I always feel every organ we have is there for a reason.
BTW I never worried about the stone getting stuck, actually the reason I had problems was because it was stuck in the gallbladderneck and it became free floating because of the flushes and it healed the inflammation and symptoms.
