Well, in my personal case, I was at a party a few months back, and consumed quite a bit of punch. Within 8 hours, I started getting a migraine headache, color dropouts in my vision, and loss of my night vision. Realizing that these previously-experienced symptoms (for which I spent several years and doctors trying to find causes) seemed to be linked to Aspartame, I checked back and asked about artificial sweeteners. Yup, NutraSweet in the punch.
