I don't do diet sodas, but my mother remembered cyclamate very fondly from before the US ban. So when offered, I tried it, and had to put it in the context that the alternative my mother had was saccharin, which is even worse. I don't doubt that cyclamate got railroaded by the sugar lobby and is probably perfectly safe, but from my very limited experience I think the newer alternatives are probably better. (I've tried Diet Coke recently, and if I weren't paying attention I might not notice the difference.)
