I bought some Zymex II and took four. Next day I took six and experienced a little bit of grumbling, but nothing major. For a couple of day I took eight of them in the morning on an empty stomach, nada. Perhaps the scolex is deeply buried, and the Zymex couldn't reach it.
I've seen and felt the moving lump parasite thingy around my naval and between my ribs. I can feel something poking me like needles too. Although I've gotten rid of most of them, and I feel great most of the time, I know there is still a big one hanging on for dear life and I want to get rid of it too.
