Research is not necessary when you can verify cause and effect for yourself. Every time I have had Aspartame in the past five years I have had a pounding headache within 2 hours. Sure a dozen or so episodes could be a coincidence, but I have enough personally collected data to convince me to avoid it.
Cheers...
Mase ~ Of course, people have managed to convince themselves that aspartame causes ... headaches...
See, Go_Raiders, you don't actually get headaches, you've only managed to convince yourself you get headaches!
