I know some of them have changed to Splenda but the after taste is still there. I have been trying to watch my sugar and carbs but I just can't handle diet drinks regardless of what they are sweetened with and I've tried a bunch of them but they're all the same. I am basically relegated to nothing be water as even fruit juices have too much natural sugar.Arnt they using sucralose (or splenda) insted if aspartame. I heard by making the change it makes Dite coke better than it was when it had aspartame in it.
