Sounds like your ND is better than average…
However like thomasjoel stated, the nystatin likely won’t cure your infestation because it only has like a 50% or less success rate. Candida adapts to almost all antifungals and hides very well when it faces them. My ND feels nystatin makes candida go deeper in the body.
Additionally, there is no way to completely kill all of the candida in the body because we need it to survive. The goal should be to change the form of it from pathogenic to non-pathogenic with no relapse. The no relapse part is very hard to achieve from my experience but my ND does know of how to do this. Unfortunately, the FDA has been cracking down on shipments from the EU for german homeopathics, so this may become unattainable for me in the future.
