I started flushing two years ago at the age of 25 out of pure curiosity. It made dramatic improvement in my health and physical form. I have never had any gallbladder or liver problems. I flushed huge amount of stones out.
I flushed every two week utill my 4th flush which produced no stones. Since then I flush every two-three month for maintenance. Usually I can feel that something is not perfect (discomfort after meals, little red spots on my face, etc.), I flush and all the problems disappear.
