Cola Light, or Diet Coke (depends what country your in) .. contains Aspertame,
which is discouraged by Atkins, because it can cause sweet cravings (others
will be better informed then I on this). I switched off of Diet Coke to a diet
cola that is sweetened with Splenda, and eventually, was able to "kick" the
habit of diet drinks altogether.

Hope this helps,
