can ferrous sulfate overdose be a cause of memory loss or memory degeneration? i know a friend who overdosed himself with more than 50 capsules of United Home ferrous sulfate in a suicidal attempt. Luckily, he's still alive. he storied to me that after few hours of overdosing FeSO4, he vomited and his stool became very dark brown. After that, his life became normal although he's complaining that most of the times, he suddenly forgets facts/information which he already memorized or been too long to know such info. There are also times that when he's too much drunk, he can't remember any detail or any information of things that have transpired when he became drunk. i hope you can help me.
