Hi, My guess is that candida's toxins cause a 'short circuit' in neuro transmitters, like a loop in thinking. I was a victim to it for some time. EFT, the tapping therapy, seems realy effective for it and seems to shake the obsesive thought out and away, but you must do several rounds of tapping, especially the first few times and not get discouraged. Do the obvious things,like keep the bowels open and drink lots of water, to keep clearing the toxins. Later it works more easily and quickly. Good Luck, love and light, Deotima.
