I too have a serious disease, as I said cll, cancer of my immune cells and Breast Cancer and severe breathing problems....... I make my own silver, it is better then all the Antibiotics I have had to live on for over 30 years. Cll seems like the best thing ever, it is amazing !!!!!! I just hope it keeps working for me and my family, we all can't believe what it does for us, our friends and animals.
