liver flush: headaches, increased blood pressure,no results

Tried gallbladder / Liver Flush with the apple juice cure.
Second day got headaches (maybe needed to drink even more than the almost one gallon/day?) and blood pressure increased uncomfortably. Third day all those negatives disappeared and normalized. But after the olive oil/lemon push I did not see any results like green pebbles. Does that indicate that I have no Gallstones or little dirty stuff in my gallbladder?
Feel otherwise very good after the 'cure'.... Tweet
