Thank you so much for your reply. I've been having computer problems for several days or else I would have answered sooner. Thank you for all of the info on these parasites. I am following the directions now. I'm hoping it is working because i haven't seen any in a few day or so. I'm really not even sure what parasites I have anymore. I think I may have more than one kind. Again I really do appreciate all of your help and info. I feel much more hopeful now than I have in many months.
