As far as I know, when we are referring to die off (also called Herx reaction short for Herxheimer), we are referring to the various symptoms caused by how killing candida causes the heavy metal and toxins to be released.
Here is a quote taken from the site above: ---------"However, there are a few things you can do to slow down this reaction or expel the toxins faster."... "Cut back or temporarily discontinue antifungal supplements.
Antifungals work by breaking down the walls of the Candida yeast cells, which then release the many toxins that the Candida has been producing. Reducing your antifungal dosage will cut down the amount of toxins being released into your bloodstream. When you feel better, you can start to increase it again."
