thank you for taking the time to respond and i appreciate your advice and the previous respondents' advice a lot. i'm a bit scared and sceptical of the zappers, tho The Master Cleanse sounds scarier. i am definitely feeling the diatamaceous earth is working and have adjusted to the fact its gonna take time. the exercise bit sounds important too - i sort of dropped all that when i first got this. the pharma drugs made me feel too ill to exercise and then you get a sort of body hatred that makes you feel you cant do nothing til you clean. its a psychological battle too, i guess. as for my initial question, i guess you dont need to ask it when you know they're gone...or at some normal acceptable human level where they dont make themselves known to you. i am so unimpressed by doctors too - i think the vets understand it best. doctors seem to have forgotten we are animals too and think we are above all this. and yet, with all the autopsies that must be carried out, you'd think if parasites were that common, it would be noticed. are they just too polite to talk about it, or maybe it's not that common after all?
