Your immune system is strong and is working like it should. One of the body's ways of quickly removing harmful things is to have diarrhea. Your body is still cleansing and the diarrhea should subside soon. If you can handle it - don't take anything to stop the loose stools. Make sure you stay hydrated.
The anti-candida formula looks pretty strong to me - the gentain and black walnut being of the most concern for resistance. You might want to wait 90 days from the last day of your HUMAWORM then take it.
