Response to Parazapper: I used one of Don Croft's small zappers. I wore it for a month continuously and definitely saw results with eliminated stuff. I'd strap it between my shoulder blades, legs, waist... During this time, it felt like I was chasing more worms (or whatever!) to my head b/c the pressure would increase. When I wore it on my head, it seemed to aggravate things and it felt like bees buzzing around my brain. I want to get back to zapping but a little nervous about it now. As mentioned, the dizziness was debilitating.
