A quick word to the wise: I thought I had scabies for about six months last year. Turns out NAC supplement was making me itchy. I highly recommend - especially if you've been doing all the de-infestation protocols and they haven't worked - stopping absolutely everything that isn't essential to ingest. Might save you some time! If that's not it, I wish you the best of luck trying out MMS, which seems to be marvellous.
