I used to drink 2-3 44-oz diet pepsi cups every day. I soon was having seizures that sent me to the ER a couple of times. After months of trying to figure out what was causing the problem, I eliminated Aspartame and within 2 weeks all of the symptoms disappeared. So I am glad to see Aspartame being used less. Obviously, diet drinks of any sort are not healthful, for reasons mentioned by Calzones and others above, but it's still good to know market pressure can drive companies to dump FDA-approved additives for what the public experience has determined is a safer alternative.
