I tried to find more information about your "double flush" - can you put a link to your post?
I've done 20 flushes so far and think I am near a clean liver. Needs perhaps some 3 ore 4 flushes more. I started nearly 2 years ago, my health has improved thanks to liver-flush. I think liver-flush is one of the most important methods towards better health! Should be mandatory for everyone!
