Any cola/soda (especially diet) tends to be sweet and make us (meaning we diabetics) 'remember' sugary foods and makes us want more sweet foods, which we know just isn't good for us. But... I really do believe in "moderation in all things... including moderation" and so, if you are craving a soda (or moreso, craving something sweet and a glass of zero-carb soda will truly fulfill that craving) then yeah, go for it... but just please remember portion control... at least be mindful of it...
In my personal experience, diet colas make me want more sweet or high-carb foods, and from this forum I think that's a pretty normal experience, so it's best to avoid them if you can; but, if you can get yourself to see them as a 'treat' and push-off any other cravings, then sure, go for it.
