Yes, you sound just like me too. Underweight, parasites, adrenal fatigue, candida etc... I had a hair analysis done and I too have copper toxicity. First of all, you need to be gluten-free because you need to addres the constipation issues. I would also suggest Traditional Medicinals Smooth Move Tea. This is actually helping me eliminate parasites now and I have been gluten free for a year. I was so stopped up I would get a colonic and hardly anything would come out. Also, drink the Moreless Alkalyzing Mineral drink (look it up on Curezone). The drink has helped me immensely. All the herbs in the world will not work until you get your copper levels normal. If you have the money go to an Alternative Doctor or contact me privately and I will give you some tips that have worked for me.
