1) Have you been diagnosed with Candida or feel that you have any sort of Candida? Since you mostly got healed by pro/prebiotics, it could be that there was an unbalance in your gut flora.
2) Do you have any oral thrush? Yellow coat on tongue, enlarged lymph nodes, etc?
3) Have you ever performed the Liver Flush or went on any Candida diet? Did anything changed for you?
4) Do you have acne? Personally, I have moderate acne, and I am certain that Candida could have played a part in my acne..
