Fever is a side effect of dead worms that release bacterias and viruses that go into blood etc. You should have doxy at home at hand and some anti virals. Also natural Antibiotics and antivirals are good, like berberine, oregon grape root, ginger, chaparral, wild oregano oil caps etc. Also coconut and hemp oil are great (internally). A half-quarter teaspoon Epsom Salt orally in the morning in fresh lemon juice and orange juice AM helps a lot too. Also enemas can help with die off symptoms too, as well as organic spirulina (3-30g p day) and chlorella/activated charcoal when you feel extremely bad.
