I read many posts of people saying it worked for them. I did two rounds and was very careful about not eating close to taking it, usually 2 hrs before and 2 hrs after but it didn't help me. But I decided to do a third round but I still have pinworms crawling. But I would still try it if I were you because it did help so many. After I finsih this round of extra strength humaworm I'm going to order "Clear" by Awareness Corp for $75.00. Doc Sutter and others said it worked great for them.
