I used to post here regularly while I did a solid year of flushing once a month (oct 2011-2012). I passed a large quantity of stones during that time and that cured my back pain symptoms. In 2013 I flushed a couple of times earlier in the year and didn't see stones. Recently I started to feel a slight twinge in my neck and decided it was time to try flushing again. I did a week of prep with malic acid and the usual Moritz/Clark flush and saw quite a lot of small mustard colored funky looking stones. They look really old (newer ones look more emerald green, I think), so I suspect that rather than new stones from my gallbladder that have been made in the last year, they are old ones that have travelled from the darkest recesses of my liver and finally found their way to freedom. Once again my symptoms are gone. I've seen so many stones there's no way they are all from my gallbladder. My liver must have been stuffed with them like an olive loaf. No wonder I had lower back pain! I used to think it was my posture but it's totally gone, as is my upper back and neck pain.
So glad to have found flushing. I don't need to do it regularly any more but will do it when my body tells me to.
Thought I'd post as I know I'm interested in people's long term results.
