So have you started the strict diet? If you haven’t, I wouldn’t do the antifungals until you start the diet because its just going to waste.
If you have really bad symptoms during the diet, one of the best ways to completely reduce it is to do a sauna, steam room, or hot tub; this will allow the biggest organ in your body, your skin, to extreat the toxins. Also, molybdenum and the probiotic will help with the die-off period as well. I was very ill for 2-4 weeks myself.
The more you cheat, the longer your recovery will take.
