It seems like you have been doing a lot of good treatments but are not satisfied with the results. For control of parasite problems Hulda Clark advised treatment for the whole family including pets and continuing on after the initial treatment with both a maintenance program and using other supplements for the parasites not killed. Good bathroom and kitchen sanitation is necessary as is cleaning the home of any sources of reinfection, such as parasite ova in dust, trapped in rugs and from undercooked foods, especially meat and fish. See the CZ parasite Forum
There are many detoxification programs which work well but I have found it necessary to also remove as many sources of pollutants and toxins as possible from my living environment. For this I followed Hulda Clark 's cleanup advice as described in Clark's The Cure For All Diseases .
