You can have lots of die-off just from depriving the candida of its favorite foods, so I would definitely wait on the antifungals until you get your molybdenum.
My die-off seemed worse the longer I was awake, as I recall. Luckily for me, I have an on-call contract job, so I had lots of time to lie in bed during the worst of things. I took naps whenever possible and always seemed tired anyway. A lot of my die-off was brain fog and dizziness, as well as a few days of flu-like symptoms and some anxiety. Some aches, but it’s hard to say what was all the sleeping/loafing and what was die-off.
You can try taking vitamin C, too, like 3000mg/day.
