well is is very discouraging wha you experienced with your first fluh. However - and I am hoping very much - that your are not offended if I will speak frankly to you.
I am NOT astonished that your Liver-Flush did not work. If the colon hydrotherapy did not work because of you were too bloated and presumed that the therapist was sort of experienced I would image the reason why your flush did not work was because of a long standing backpressure upon your liver.
If bloating - in particular a long standing bloating - is your reason for starting Liver Flushing it is really necessary to prepare the colon beforehand. I did a three month preparation with colon cleansing and was a real rope forming factory during this period. So I can look back a very good experience, if it comes to bloating or dysfunction of the colon.
I would recommend to start with a colon cleanse. Also try to accustom your liver slowly to olive oil mixed with lemon juice or orange juice. Try Oxypowder or colosan before starting a liver flush. First the toxins in the colon need to be removed via bowl cleanse after this one can start Liver Flushing and only after the liver is clean toxins in the body can be mobilized.
Try to drink now as much water as possible. Give yourself an enema, take Bentonite or activated charcoal with you can get this easily - it is omportant to get as much toxins out of your intestines -preferably as quickly as possible. Then don't start your second Liver-Flush until a thorough bowel cleance have been done for at least a couple of weeks.
