Thanks for your reply. I haven't seen any critters alive or dead. So I'm thinking this is not the magic bullet, but i have a 1 1/2 wk left on the treatment so after that I'm planning on doing The Master Cleanse diet augmented with Essential oils and light therapy proposed by Stanley Burroughs. If that doesn't work I may try the horse dewormers as you suggest but really? I'll run it by my naturalpath. I was also thinking about hydrogen peroxide therepy but that is pretty extreme to me. I'll post if I get any results.
