well. i think everyone who doesnt regularly drink diet feels that way. but once you get on diet, and start drinking only diet. you cant go back.
my dad was on atkins, so we only had diet in our fridge all the time, my brother and i hated it. but then we just started drinking it out of necessity. now, my brother and i wont drink anything but diet.
also my friend brady who is diabetic, he drinks only diet for obvious reasons, but he said even if he wasnt, he'd prefer diet.
