I would say my samples were pretty textbook too. It's a sad state of affairs, isn't it. One of the things this integrative doc talked about at the lecture was taking charge of one's own health and being your own best doctor. Of course I have been doing this, but always in the back of my mind I was hoping for a safety net. I guess I now realize I'm to be my own safety net. So far I have done okay, but I think I stumbled when I stopped cleansing. That's when the brain fog came back. It's very true what you say about them affecting your cognition and messing with your head. I think I'm getting my head back on track again, though. Thanks for your thoughtful reply.
