I have done several parasite
cleanses. My last one I did for 6 weeks and didn't pass them until the 3rd week. Then it was like a flood, gross!
I think it is very hard to get rid of them all. Just one parasite
can lay something like 10 million eggs a day.
I plan on fighting though, and will keep on cleansing, as I feel better.
I would, personally, not take any Rx to get rid of them. I think the side effects are too much. My stomach is much better after drinking raw goats milk kefir, 4 cups a day, and taking a lot of probiotics. Just my opinion.
