It's probably the caffeine in Coke that keeps you going back. By the way: the newly reformulated Pepsi Zero has a lot more of it.

There's Coke Zero Gold or Zero Zero (depending on the country). No sugar, no caffeine.

I'm still addicted to the taste.

Yep, I do know about those, we have them here in Canada.

Something tells they're much, much less popular than their caffeinated counterparts.
