Hydration: Make sure you're well hydrated, Dizziness has many causes. If severe, or you are unable to walk, you will need to go to the ER. If mild, and self limited, probably ok to observe, and consider seeing your primary care at the next available appointment. Hope this helps!

MSG: You likely had the FDA approved poison, MSG, added to your food to intensify the taste and now having the typical reaction. Yes, it is temporary and will not cause permanent issues, but next time request no added MSG.
