Everything below the link is from Rich, so it's mostly just Rich. I used different fonts to make the distinction. Part of the reason I didn't put his quote in quotes is because the post is more narrow horizontally and so it takes up a lot more space that way. Also, if someone wanted to quote part of my post including what Rich said it would be easier than if it was in quotes. There's actually a lot more information in that thread I linked to. I haven't really read through it myself. I have a lot of links threads and articles saved in a text document which I plan to read at some point. There's just so many aspects to health that I'm not sure what to concentrate on. I started experiencing an abrupt depression about 4 months ago. After a lot of research I seem to have traced it down to inflammatory cytokines as the cause of my depression. It's possible that Lyme is also directly causing my depression by affecting my CNS, but it seems that anything that causes a herx (including probiotics) causes the depression. I supposed I should be thankful since I knew absolutely nothing about cytokines or Th1/Th2 immune responses before this happened. Depression can be a huge motivating factor. I still don't really know what cytokines are. Not even close. But at least I know more than I did a few months ago. I've stopped a lot of my immune system supplements because it seems stimulating the immune system might be counterproductive for me at this point.
