Hello - You are having die-off symptoms. The body gets rid of toxins by rapid elimination - vomiting and diarrhea. While parasite cleansing, the body will tend to develop loose stools so that the parasites and toxins can quickly leave. You need to keep your body hydrated - drink at least 2 quarts of water per day - this helps flush the toxins out faster.
I don't know how many laxatives are in your formula, but if the loose stools get to be too much - try using some PLAIN psyllium to help bulk up the stools. You can take up to 10 grams per day, just don't take it at the same time as your parasite cleanse - you want them to work together, not against each other.
