I am so sorry! It seems like you have a terrible case of resistant ascaris! I tend to agree with you that environment, medicines, and chemicals also have a hand in producing these strains. These types of infections are rare, but they do happen. I wish I knew of a better way to get rid of them - a faster, easier way - but I do not.
I can make an extra strength dose for you - maybe something with extra wormwood since it works topically ON their bodies instead of IN their bodies. It's just thought - if there is anything I can do to help you - let me know.
