You are not far off. It is estimated that 25% of the population is sensitive to NutraSweet (Aspartame). A small percentage of these being potentially fatal reactions (stroke, anaphylaxis). You will find plenty of people to sign up for your new group. Many of the people won’t even know that they are sensitive either from mild symptoms or blaming it on something else. I discovered that I was sensitive after not having NutraSweet for about 6 weeks then drinking a diet soda water. I developed a raging headache. One can build up a tolerance to anything when under constant exposure.
