I think I've always been slightly sensitive to MSG, but last night I came home feeling fine (if exhausted from a bartending shift at an art event), ate some Thai food, then immediately had to pass out. I woke up feeling energetic again, ate leftovers at 11, and am feeling like I've taken a Benadryl or something.

Anyone experience hypersensitivity to monosodium glutamate? Given the presumed importance of glutamate in post-concussion syndrome, I guess this does sort of make sense..
