TRUST ME, if you had a parasite, you will have never gotten rid of it, through zapping. GIVE ME A BREAK. YOu probably had nothing or just some irritiable bowel disease. And please stop telling people that they can get rid of parasites through zapping. BEcause you dont know what the heck they have.
And zapping is not some universal cure for all parasites, which require different medications for different durations, which can done under the able hands of a competent doctor who knows how to treat.... I know you mean, well, but your advice is more harmful than helpful to people who come here for real help.
