Hi I also havd had a bad experience with the Paranil, if I skip one day I feel the parasites moving like crazy, It must not be strong enough because when I did teh Clarkia cleanse a few days later I could not feel parasites at all, I am going to return the other 30 day cleanse that i bought since i am not happy at all, I think I will just do the Clarkia cleanse and order Oxypowder .
