Disappointed, no parasites

I have been zapping for a while with a homemade Clark zapper and wondering if it worked as nothing noticable happened. So I bought a manufactured one which certainly works in that it burns my skin if I don't use enough wet paper on the copper electrodes (the homemade one doesn't do this), but I have seen no parasites come out. Admittedly I would freak if I did see some, but I need to get them out. I'm wondering if the new zapper isn't working either. I also do the parasite cleanse weekly as Dr Clark recommends with no parasite sitings. Any ideas? Thanks Tweet
