Let me put it this way. The doctors gave me six months to live. I told them I was taking charge. I started drinking distilled water lots of it and I removed the air lines in my nose, I was on five leaders, stop the pain shots, stop the 18 pain pills a day and drug patches. Remove the 16 electric patches from my back. It now has been three years and I feel like a twenty year of age. I'm looking at my seventh decade. THIS IS WHAT DISTILLED WATER WILL DO.
