Since when is Sucralose better than Aspartame?
Ask someone with phenylketonuria. I once went to a restaurant with a group, one of whom has this disorder. When he ordered a drink, he specifically said "NOT diet, I can't have phenylalanine". They brought him Diet Coke. He drank enough that some time (maybe twenty minutes) later, he had a freak-out and would have gotten all of us tossed out if he hadn't had enough sense to explain to us what he thought was about to happen. The restaurant quickly reversed tack to make sure they weren't going to get sued, while one of the people in the group had to drive him to a hospital to make sure he'd be OK.
