You're right about them tasting foul. I don't think anyone who likes a regular soda ever tastes a diet soda and says, "Oh! That's great!" No. The best you ever hear anyone say is, "Oh. Not too bad." Or, "I can deal with that if it helps me lose weight." It's definitely an acquired taste. Like cigarettes. But who wants that? And still, these things are addictive and they sell.
