I am a victim of Aspartame/monosodium glutamate (MSG) poisoning. I use to develop headaches all the time. My symptoms ranged from minor headaches to migraine headaches and vomiting. I also have memory loss.
Once I discovered the cause, 95% of my headaches went away. I read product labels and avoid Aspartame/MSG like the plague. Try as I might, I still occasionally get poisoned due to the use of these drugs by restaurants and/or disguised labels. I am very concerned about this occasional poisoning because in addition to getting a headache, I also feel as if my mind gets very cloudy. Memory recall and concentration are definitely affected as well as vision.
