Hi Robbie. I'm curious - what do you mean exactly by brain/eye fog? Headaches? Fuzzy vision? trouble with memory? I know that in chinese medicine the liver is connected with the eyes. I have REALLY dry eyes, and I know it's liver. I can't tolerate contact lenses at all. I'm hoping I will be able to once I get my liver cleaned out. Am also hoping my headaches will get better. I'm doing my second flush this weekend! Hoping for good results like yours. The first one was productive, but not as much as I had hoped.
