You sound a lot like me. I have high bilirubin, liver issues, low HCL, low pancreatic function, adrenal issues and I suspect high copper although I have not done tests yet. I also suspect estrogen dominance.
I am finally able to tolerate HCL; I was so low, I couldn't handle a full pill.
I am wondering what brand of HCL and enzymes you take?
I've been on the zinc for about a month now. I've seen some improvement in my energy levels. It fluctuates a lot. Sometimes I have had really good energy while not so much at other times. I am still figuring it out because of the complexity of my issues.
