A few summers ago I began to have a severe reaction to the sunlight on my skin. Burning (as a chemical would), swelling, itching and then the days following the skin exposed to the sun would peel away. I thought I was having a reaction to a new sunscreen. After complaining to my mother, she reported once having the same problems. Her pharmacist told her she was experiencing an apartame overdose. I quit the diet stuff, and after a couple of weeks I was able to go back outside. What a relief to find out such a simple solution! I'm convinced the stuff is poison!
