Seems like alot of people do, yeah. Much more than the doctors care to believe.
The problem with today's diagnostics is that they test feaces for eggs only, not parasties. You can take (as I have and many here on Curezone) stool to the doctor covered in worms easily seen to the eye... but you won't be diagnosed with parasites because diagnosis is not made by a doctor's eyes.. it is made by a machine which looks to detect for eggs only. Eggs often sit inside the body and don't get flushed out into the faeces.
