Immune weakness can allow both parasites and candida to grow. I recommend taking the drugs to kill the parasites and then getting the BioElectric Candida Zapper to kill the candida. Limit intake of sweets and always salt your food (because salt is anti-fungal). I've had candida all my life and have tried many things against it. The Candida Zapper is the only thing to work well and so I highly recommend it.
