I know about the blurred eyesight, go through that all the time. Somedays I have blurry vision and I swear on some days the colors are brighter. My hair is really coming back thick and growing like crazy at the moment. Could be all the supplements I take or maybe I should take it as a sign of things getting better. It's really hard to be skepticle with this mercury crap. Never know from one day to the next what symptoms are going to arise.
