I have been seeing a nutritional doctor for about a month now for mineral balancing in my system . He has me drinking distilled water with 2 fresh squeezed lemons per gallon a day . This is used to balance out you're P.H. level's in you're body . Too much acid in you're system will have consequences in the long run . At first , I had terrible heartburn , but I alway's did anyway . But the distilled water , and fresh lemons has caused my body to balance out my P.H. , and rid me of my heartburn . This also is a great way to cleanse you're digestive system , and oxygenate the cell's in the body . Just a little info from my doctor visit's . Mike
