Supposedly, it is possible to die on 200 mgs. I have never read about anyone dying from it, just getting cataracts. I don't really know what I'm doing, but I thought I would try it anyway. It is rough, like you would not believe.
How do you think The LDLo is the lowest recorded lethal dose was figured out.... Lethal meaning death. You know why it has been banned since the 90's because it can kill you or cause a variety of other problems.
Are you taking proper vitamin supplementation

Magnesium, Vitamin C, E, Alpha-lipoic-acid???
Magnesium (1500mg)
Vitamin C (3000mg in divided doses)
Vitamin E (1200 IU in divided doses)
Alpha-Lipoic Acid (500-1000mg daily in divided doses)
I don't have my other info with me but, those are some good numbers to aim for if not higher. I would stop taking it if I were you or at least lower your dosage, you are playing with fire.
Be safe
