MSG, could it be?

Yesterday I had a strange experience at work. I ate (many) nacho corn chips in the morning tea provided and discovered that msg or preservative 621 was used as a flavour enhancer. During the rest of the day I noticed symptoms such as:

  • headache
  • bloating
  • drowsiness

I don’t know if it had to do with the MSG I consumed earlier that day or if I was purely just getting sick. One day on, all these symptoms have gone away.

Could it be that I had an adverse reaction to MSG? What do you think?
