Yep I think histamines (not copper) kept me up last night. I noticed I was dehydrated too and finally Sea Salt / water sent me off. Of course adrenal fatigue will cause histamine problems too due to how it effects our hydration and electrolyte levels.
The question for me is whether i will have to watch histamine / dehydration / electrolytes / copper for the rest of my life. I think YES but thats no bad thing all things considered! In other words it seems to me that the adrenals dont suddenly one day after much healing reach 100% and you dont need to worry about things any longer. Similarly with the leaky gut - I dont believe reintroducing former allergens such as soy, MSG, gluten etc is wise EVER even if the intestines are healed.
