Yeah, I believe adrenal fatigue has a lot to do with the body fighting the parasites, bacterias and viruses. It can be chronic in the sense that your body can't kill off the parasites and viruses, but keeps trying. Or then it can come and go like for those who remove their fillings, and finally improve in the end. In both cases your body is in a very stressed state most of the time, which isn't nice if you ask me.
