Basically i took high doses of niacin b3 the flush kind for depression after watching food matters documentary and everything was going well i felt better than ever after a while i began to experience zero anxiety and apathy and like adhodenia and i feel like in a different state of mind also i begain to have weird thoughts that i didnt have before taking the niacin at 3g and i didnt really work my way up i think i started at like 500mgs it changed my life for the better but then i begain experiencing the weird symtoms. i take a full multi coenzymated aswell but i know it all started with the niacin one weird symtoms is the inability to laugh and i also dont experiance much adrenaline not even when i work out if anyone knows whats going on and what i can do i would appreciate the help. some people on other forums say that its a possible that the niacin detoced heavy metals but i am unsure.
