Looks like we have some things in common. Especially the inability to digest grains or fruits. First of all, no, dr Wilson its not the only source talking in detail about liver. There are plenty of other pages discussing it. We got a liver rampage back in the day in my forum "of origin". http://recover.forumup.org/viewtopic.php?t=2506&mforum=recover
Basically if your liver its screwed, more likely than not your GI tract its to some degree screwed as well. The problem can originate in any of them. Something started a degenerative hormonal and bioquimic loop with us. Because bad liver health will impact all hormones in the body, estrogen its the first that comes to mind, and digestive system its strongly related with neurotransmitters. At the end, with this scenario, you will develop some degree of adrenal fatigue, or you already have it. It would be useful to get cortisol saliva 4x spread tru the day,pregnenolone, progesterone , ACTH, DHEA and DHEAS. But probably a mineral hair analysis will tell you the same and more for the same money more less.
I am about to begin nutritional balance with Dr wilson, btw. I have tried some things (hmm haha not "some" ok I have even done urine enemas) and after all this journey, I have realised that regaining adrenal health, balancing the autonomic nervous system, detoxing heavy metals and minerals in the oxide form, beating candida and other pathogens (parasites, h.pylori), getting proper nutrition and digestion (leaky gut and constipation/diarreah), getting liver in healthy shape again are overall what I need (and most of the people). I do not expect nutritional balance to do ALL this for me. Even if it just start slowly repairing my adrenals, addressing some electrolyte and mineral imbalances and detoxes heavy metals I will be so happy. Because I suspect heavy metals are one of the main culprits of my problems.
Do the coffee enemas, I assure you they wont affect your digestive tract. I did them for a while. They are powerful. My stools got darker because of more bile release (this is good) and I passed out some candida strings and even weird looking things which probably were parasites. During this time I was doing "egg flushes". Stopped doing the enemas because it was pretty messy to do and they aggravate my prostate pain, sadly. But I plan to start again and hold on.
I encourage you to look Liver Flushes in this site. Contact or read the posts of Michael B and others on the subject if you have doubts.
Oh almost forgot it the best remedy for liver that I know its LiverLife by Bioray which contains truly healing things like chinese medicinal mushrooms. There is some feedback here on curezone and in otehr boards.
And I would start taking raw milk kefir and sticking to a paleo/drwilson diet ;)
