I know you posted this forever ago... I hope things have cleared up for you! I just wanted to leave a note for you, or anyone else reading this thread, that pin-x contains aspartame, or phenylalanine- which can cause severe complications in people with PKU or the PKU gene. I don't know about just that single dose, but thought I'd mention it. parasites are no fun, but just about everyone has them and its really crucial to get clean and stay clean, for our health and longevity. Blessings!
