Well if you have candida for 15 years - like me - then you know how resilient it is. Eating grains - baking muffins??? - and falling off the wagon once a month I would think is enough to maintain candida.
In my own experience, actually you can bring your candida levels down down down and a little sugar, a little carbs is enough to be back at square one.
But what are your symptoms anyways?
Mine also seems to have become resistant to a lot - GSE, essential oils, do NOTHING at all. Garlic is still working a bit but due to all the inflammation in my digestive tract I can't have it. Pau d'Arco is good.
Candida is so bad and so resistant for me I had to relocate to the US to get alternative treatments (with IVs, chelation, peroxyde injections, etc)
As for the Luneferon, I am also weary : a flea medicine??? And of course, websites selling it as an antifungal promise miracles as usual.
I am getting desperate enough though to want to try anything.
