To be honest, my practioner is not great but living in Australia, I'm limited in my selection. Think mine is like Theresa Vernon except he is open to trying cheaper supplements and is honest about other brands being the same. However, he pushes enemas etc which i don't use despite having bought an enema bag ready for use, but found i don't require it, my body just can't handle any impact from a strong detox yet.
However, I am finding that I am doing just fine without a practitioner in general because of this forum - it's been a God send. This forum is my practitioner! So i've been doing extremely well with advice from here and the supplements from my practitioner. I think most of it is a trial and error and having people tell you their experience without a commercial interest is an amazing added benefit. Think the forum has also been extremely helpful because in addition to their NB path to recovery most people here have been suffering other chronic related illnesses for so long and so they bring also a wealth of experience on related matters which i have found extremely helpful in the recovery process. It's like accessing a bag of goodies (advice on all related matters)ready for dispensing to others.
