HUMAWORM is strong - stronger than any off the shelf parasite cleanse. You are having die-off. Drink more water - take Tylenol for the headache if you need to. Make sure you are having regular bowel movements as the toxins need to come out in your stool. Take a dose of epsom salts or ex-lax if you need to. This will all go away soon.
HUMAWORM is pulling out parasites and toxins from ALL over your body. Ascaris roundworms incubate and hatch out in the lungs and it is common to sometimes cough up one during a cleanse.
