The three (3) tapeworms I passed were at different times. I did one round of Zymex 11. I took 2 capsules two hours after eating a meal. NO FOOD any where near taking the Zymex 11, or you won't get them. Then I waited a week and started the next round of the Zymex 11. And so on. . .
I don't know about tapeworms playing "King of the Hill", or not allowing any other tapeworms into their territory. All I know is that these things had the inside of their heads digested and had part of the tail on them. That part of the tail had been mostly digested and was mostly transparent. I could see their TEETH! Their heads were about as big around as an American Quarter dollar. I have pictures of them that I took when I put them on my scanner. I keep my "proof" of what happened to me in pictures in a folder.
