Fluorescent light messes with my eyes as well. I swear they're making me go blind.

The thing about MSG is that it's just an amino acid with a sodium attached. I'd be more than willing to be it's more because the people that get palpitations and headaches and such have a negative reaction with too much salt than an amino acid that is present in every single food that has protein in it and also one that the body requires as part of the metabolism.

EDIT: If you have some sort of negative reaction to glutin, that would probably do it, as well.
