I don't understand the question. You mean about the vitamin deficiency/food intolerance comment? Yes, in that I was refering to you.

The only time I've heard about brains zaps is in relation to people withdrawing from antidepressants (and I guess benzos and sleeping pills too). But that tells you that some chemical changes can cause this sensation. It's worth investigating, I think. If you could find a vitamin or mineral deficiency that has that symptom, maybe you'd have an important clue.

Or maybe this is happening because you've been abusing benzos and you've stopped taking them?
