YES! I started getting migraines in ’88. Before that time I usually drank 1-2 diet sodas per day and used packaged NutraSweet on cereal, etc.
It took a few migraines to realize that they were being triggered by the NutraSweet.
I got fibromyalgia/MCS in 1991, and still react badly to NutraSweet. I get the headaches, but also nausea, and the shakes. I stay away from it in any form now.
