It is purely anecdotal but I read a post here years ago about someone that had a 10 year battle with Lyme disease, had gone through rounds of antibiotics and it always came back. He finally heard that maybe long fasts (2 weeks) might help, tried it and his symptoms went away. Just mentioning it because it seems relevant. I always thought should it happen to me, I would give a 2 week fast a try, under a doctor's supervision.
