Help with die off

I think my husband is having die off symptoms. He has a mild headache, feels like he's getting the flu, pain in left shoulder, aches in most of the body, his stomach hurts and he feels just bad. I had him do enemas with 1 gallon of water. I think he is upset with me now for having him do the parasite cleanse and now he feels sick. Should he continue? He's done two weeks of Clarkia and should do the week off now. He has been passing some things that I think are parasites via bowels and nose. What else can he do to help with the die off? Should he try some P&B shakes?
