That's a tough one. You may get to know yourself after a long period of time what maybe doing what, but it's not always possible. So long as you're following a strict candida diet, you should not require antifungals, they may cause ongoing die off symptoms because a certain amount of yeast (due to mercury and low immune system) may continue to remain at a certain level. So it's an ongoing cycle of killing it and it growing back to a certain extent.

The best method is to cut off it's ability to feed and thrive. So though you're not killing it constantly, you are also not letting it grow any further. That's my view, or you maybe stuck with ongoing die off. The diet causes enough die off intially on its own without any help. It can also take weeks for improvement to show up from starting diet.

At any rate, again the symptoms may not always be known for what they are. I'm sorry but it is very hard to explain. I can usually tell the difference in myself, but I can't describe it because it may cause "fatigue" but the KIND of fatigue may differ from oneanother.

I'd just be careful of antifungals, they'll be spilling toxins into your bloodstream/liver continually from killing yeast that is continuing to grow back from mercury/immune problems. Just use the diet, or you maybe overwhelming yourself with die off toxins, PLUS movement/chelation of mercury.

also, it is recommended by some that one should not even START antifungals, until they have been on the strict diet for about 6 months or so. However, it's unlikely you will ever cure candida unless you get rid of the underlying problem (which for you maybe mercury). So there is not too much point in using antifungals constantly.

I used to get too sick from them anyway. Vomited a few times. It just poisoned my liver too much and then the toxins from that, would then lower me even further and of course the yeast would thrive again from that and the cycle continues. Antifungals maybe more effective after a temporary condition, rather than an ongoing one.

It's up to you though. But you may not know what is doing what if you continue taking them. If you do the diet and chelation, you may find things are not as intense.
