Did you feel any different or notice change as it was dying off/reducing? I was treated for a fungal infection a while ago with some anti-fungal drugs and the side effects felt huge, but the doctor told me those drugs are considered very mild. It made me wonder if the fungus was affecting the way I feel and it dying down made me feel differently (better, but it was a big change).
I was also on antifungals and yes it was quite brutal. I was quite tired and had a red flush from the die off. I took off the shelf liposomal glutathione to help clear out the oxidative stress.
