I was wondering if anyone knew that they had a toxic reaction to taking too much B6 at a high dose for too long? That they had a reaction of a shock, that ran in a current. I think its best describe as a electric current that ran a course. I felt this shock in 4 different spot and then it was repeated. It ran from my diaphragm to esophagus to my heart and to the back of my head. (I had been ill for about 2-3 months after I had ingested three months of 300mg. of B6, when this happened.) After I felt that shock, food or fluid got stuck in my throat. The Mayo Clinic found my lower esophagus muscle too relax. My physical body has continued to be ill. All of the areas that felt the shock have damage to them, but not seen right away. My autonomic nervous system is compromised I have been told?
