Esstee
I don't know anything about copper(so I can't help there). Though I would highly recommend an good probiotic to help with diarrhea. I'd also recommend increasing your daily water intake to help regulate ph and/or taking a baking soda + water drink once per day as an alternative.
Whatever the case, its important to flush your system out with plenty of water when taking
Miracle-Mineral-Supplement . Otherwise, the changes in ph along with the waste produced by
Miracle-Mineral-Supplement could put undue strain in your kidneys.
Hope this helps.
