By the way, I am not sure if LDN acts on your immune system in such a way as to make autoimmune issues worse. If you have time/interest you might take a look at this article:

They say in several things I have read that LDN helps to "modulate" the immune system, whatever that means. In any case it supposedly has the effect, at least for some people, of boosting the endogenous opioids, or endorphins, which actually can help to fight autoimmunity supposedly. Hank
