dr Schwartz thiamine protocol

dr Schwartz thiamine protocol Hallo everybody, I started the protocol on march 1st, 2022. I have the fortune to be in the 33% of the stutterers who gain beneficial from that protocol; after 2 weeks my stuttering improved dramatically. I'd like to share a side effect: the floaters in my eyes, that I have been seeing for years, have worsen and my right eye is dry. I read somewhere that too much thiamine could lead to a damage of the optic nerve, do anybody experience the same?
