So I bought a countertop water distiller to get rid of nastiness in de tap water. So I drank a small glass of it last night and my heart started racing. I had this similar effect when I ingested magnesium tabs with normal tap water after waking once. I read many stories you can safely drink a lot of distilled water, and opinions on remineralizing it differ. I added about 0.4 gram of salt to a gallon, but I read on one place it should be 2.5 gram per gallon and in a book I am reading now 800 mg/gallon is recommended. this is quite a difference. so anyone has an idea on how much salt to add/ why the racing heart?
