So I've still been having problems with what I think is excitotoxicity caused by the methylation protocol. The symptoms have definitely abated somewhat since I decreased the doses of b12 and the folates and added in L-theanine, but I'm still having issues with it. So I decided to add in b6, which was one of your suggestions, and, initially, it made me feel incredibly calm. However, after a couple of days on it, I started to feel the physiological anxiety and tension I associate with the excitotoxicity, and it was much stronger than it had been before I started the b6. I discontinued the b6, and more or less went back to my previous baseline. Any idea what could possibly be going on here? Could the b6 have been helpful, but then somehow some other part of the methylation cycle couldn't keep up and I became depleted in something else? I just wish there were a way to test all of this more scientifically.
