dear cash, what is happening to you , also happened to me. it is the magnesium,trust your gut feeling. there are a few of us out there that have "kidney damage" ,most likely from asprin or nsad 's,and magnesium causes HYPERTENSION when we take it, that's not all , it causes extreme panic attacks.it took me a couple of years to figure all this out and many hours of reading.there is VERY LITTLE info out there about kidney disease,as you will find out when you persue the real problem with yourself,good luck .
