Thanks Sieka. I started flushing because I had stiffness in the muscles around my eyes (then diagnosed as convergence insufficiency), lower back pain, and premature grey hair and hair loss (I'm 32, male).
I don't see any change in these. I realised that the eye problem and the back pain are both because of a scoliosis in my spine, which is something I was most probably born with, and most probably it is connected to a larger connective tissue disorder. So I don't think the Liver Flush will cure that, although it may help the muscles that are strained by the spine remain free of toxins and less inflamed.
I haven't seen any change in my hair.
There is a facebook forum for the Liver Flush where there are people who have done over a hundred flushes, over many years, and are in very good health. A friend of mine is on her 40-something liver flush. Andreas first recommended 10 flushes or so to be enough, and later changed that to upto 25. I highly doubt I will be in great health by 25.
I also live in a city that is among the most polluted in the world, as far as the air goes, so I think I have a large dose of toxins entering the body that I need to struggle with on an ongoing basis, perhaps all my life, if I continue living here. So at present, I plan to keep flushing indefinitely.
