I think, experiencing a complete cure after one singe liver flush, of whatever symptom you are suffering from, is an exception to the rule.
I believe most people need to flush at least 2-8 times, before they are cured, and there are also those who have destroyed their health with medications, poor diet and poor lifestyle to such degree, that they need to flush for several years (one or 2 flushes per month) before they are completely cured.
Again, those people are an exception to the rule, a minority.
But, if you base your conclusions on messages posted on internet forums, you may think that those people are not an exception.
Cause those who have a miraculous cure after just one single flush are far more likely to report that cure online than those who need to flush 5 or 8 times to achieve the same effect.
Also, those who have not found a cure after 15 flushes, are far more likely to ask for help and report failure than those who found a cure after 8 flushes.
It is just human nature.
We are far more likely to ask for help and ask for assurance when things don't go by the rule, rather than when everythings goes as expected.
