Once i removed all my Amalgams (like 5 of them) and put white fillings my eyes started feeling better in a matter of days. Less watering (almost acceptable, pupils relatively normal-before dilated). Also when I changed my CRT monitor for LCD all the monitor sideeffects also went away (for eye fatigue).
Another thing... if I don't eat for 2 days and only drink water, my body odour almost vanishes. Of course once I fill my guts with food again I'm back where I started.
Psyllium husk is what I've been taking last 6 months. Its fiber. Its used to push everything in the guts quickly. Helped a little.
