Just wondering if you changed your diet and cut out the sugar. parasites love Sugar in milk and bread. You have to starve them to weaken them. When I started an OJ fast I was coming to the end of my first bottle of the dewormer. It was day four and I had not had a bowel movement all day!! I went for a walk that evening and began drinking lemon water with stevia to sweeten. A few minutes later I had to go and I passed what I call a "colony" of liver flukes. Probably close to a 100 in two movements. It was gross, but it was worth it to know they were now out. Sometimes when people are constipated - it is parasites blocking the way.
