I would recommend that you try the HUMAWORM first - you already have it and it will help remove a lot of parasites/toxins from your body. It also has supporting herbs that will help ease any die-off symptoms.
THEN - if you and your doctor want - you can always go down the prescription drug path.
Right now, you arte so toxic that if you took the ivermectin - you would be REALLY sick from die-off - because the ivermectin has nothing to support your body while the parasite killing is taking place.
