Zoe, a lot of what you have shared are measures I too have taken and some I have not tried but will be trying for sure, I so appreciate what you have shared. My mind has been so foggy from that crown that sometimes I simply lose my stream of thoughts altogether so it's nice to have all those links posted available in relationship to this issue.
I can offer this, I don't think it is good level of health, body system purified and cleaner living etc., I use to wonder that myself and my family would tell me that I was causing my body to get sicker by trying to make it too healthy, nonsense! lol but I will explain it the way my chiro explained it to me one time when we had an extensive conversation about these very things and he said that it is a genetic predispostion in that the gene is present but it lays dormant until the wrong combination of things enter the scene and turns it on. But he also went onto say that it can be switched off with the right combination of therapies and to keep trying even though we don't think we are getting anywhere.
