I can taste ALL artificial sweetners. And they all taste vile to me.
I'm an everything in moderation eater, however, so I never see sugar or fat as the bad guys - they're just like everything else, enjoy in moderation.
I love to bake, but you won't catch me ever using artificial sweetner in my baked goods, even for my diabetic in-laws. For them, I have a growing reperatoire of recipes that use fruit and freshly squeezed fruit juice to sweeten.
Strangely enough, since FIL has been on injectible insulin, he finds that artificial sweetners do strange things to his blood sugar levels and no avoids them altogether. He used to drink diet drinks, but now I got him turned to plain soda water w/crushed fruit - leave it to sit abit and enjoy!
