I’d personally try stopping the cocoa for a while and see if you feel better. I don’t tolerate cocoa at all which is a shame because it’s delicious.This started around the time I started taking cocoa (doesn't copper use up potassium?), some selenium, and honestly I don't remember what else.
Did they check BUN, creatinine and the ratio in a blood chemistry test?But here's what I don't understand: wouldn't serious dehydration show up somewhere in my electrolyte bloodwork? Electrolytes on paper come back normal but I guess it's not the best thing to look at. Also I don't like, go days without water or anything. I still have multiple cups of fluid one way or another every day at my worst.
