Yes, the zapper helped so much in getting rid of the parasites.
I used to be very nauseated every morning, sometimes all day. Often I would get a bad reaction after eating (allergic) and the zapper helped (helps) with getting rid of the bad reaction. My nausea or heartburn goes (went) away when I zap(zapped). I still use it on a regular basis. Whenever I feel bad I use it, and it helps me to recuperate much faster.
