Turns out NutraSweet or more correctly, Aspartame, or Phenylalanine, is the culprit. Aspartame KILLS neuron connections in your brain. Thus causing short term memory loss, headaches, on down the line.
I don’t ever drink or eat anything that has Aspartame in it; it causes me to have migraines and dizziness. Plus, I think it tastes terrible, anyway, I have heard that it stimulates appetite so if you are dieting that is the last thing you want to happen.
