You can't expect to see any results in just one liver flush. That pretty much goes for any cleanses. you can't expect to clean out a lifetimes worth of crap in just one of anything. It will tame time and perseverance.
The general wisdom is it takes half a dozen or so LFs before seeing any real results and as far as getting rid of all the stones in your system a dozen or more flushes is not uncommon. It took me around 18 before I got the all clear.
