I have also tried lots of different products. I'm really, really hoping the Zymex II will work, but I've been taking it since the end of August and it has not died yet. I believe I have both Tapeworms and roundworms. But I was not taking the Wormwood combination with it. I think it is most effective taking both at the same time. I just recently, within the last week, met with a chiropractor who has used Standard Process products in his practice a long time and it along with the Wormwood combination of herbs is what he is recommending, so I am now taking both together. I do feel it is getting much weaker as I don't feel it biting me nearly as much as before. You can read lots of comments about Zymex II out on the Dr. Sutter forum, although he makes it sound like it will be dead after a few weeks, and I've heard it can take more like several months. It probably depends how big and bad the infestation is and how often you are getting cleaned out. The Zymex II digests the outer skin of all types of worms and I think that makes the herbs then much more effective at killing them. I'm also eating lots of raw pumpkin seeds (ground) and some dried figs. I've also used Diatomaceous Earth in the past and still do mix some it into my morning quinoa cereal or oatmeal. Best of luck to you on your journey.
