I have never herxed before! While I have tried multiple mold protocols, including a pharmaceutical, herbal, and homeopathic for 6 months, I have never had a reaction before. However, this supplement evoked a reaction from me at less than the dosage. I have decreased the dose, and attended to detox pathways/sequencing. Trying to figure out if this means it is actually working, or if it is not right for my body, or if its something else.
