caffeine. I end up drinking more soda than I should. Over time the sugar and other crud including caffiene in no bueno for my health. Therefore, I would have used the "caffeine free" versions to ween off the addiction. The goal, to not drink more nasty soda than needs be. Let's not kid ourselves caffeine is addictive. Coffee drinkers go wacko without their coffee. I have no issue with offering "caffeine free" versions of anything.
