I might consult a naturopathic expert, like a licensed provider of colonics. I wonder if enemas might help?

Hello,
Try ESSIAC. Google it to find out more information.
I hope it's available where you are located.
Try to find on the internet the ingredients list and the proportions and try to prepare it with the ingredients, it is way less expensive than the one ready-made.
Good luck.

try looking up some of dr. andrew weil books it helped me
