I was up to 15 drops 1x a day at night. I had to but back to 10 drops because I had bad D symptoms and they wouldn't subside. I kept thinking if I can hold on it will kill everything and I can go forward. I had to stop because I was doing a liver cleanse this weekend. Taking too many things is too taxing on my body. Now I have a running nose since I got off the Miracle-Mineral-Supplement 3 days ago. I have taken 5 drops to see if that helps.
