For the past few weeks I have been megadosing both Potassium and Magnesium. Probably around 2000mg of each per day. I have actually felt pretty good as far as mood goes, have seen a return in nocturnal erections, and a return in body hair. Libido remains at 0% however. My question is should I be worrying that if I'm taking so much of these mineral, that I might just drop dead one day? Is what I am doing safe?
