When you begin your candida regimen, be sure to include molybdenum. It is a trace mineral that helps to breakdown the candida toxins that make us feel so bad. As the candida die off, that extra moly will help breakdown the extra toxins release, and help reduce/prevent any herx reactions.
You may also want to add a combination of B5/Pantethine 400-900mg of both to also help with the toxins. All of these have made my cleanse really easy without a lot of die-off reactions.
