You never lose the taste for regular. I drink a regular coke like once every few months because Mexican Cokes are great, and they are damn good, but I know if I drank them on a regular basis (once or twice a week is regular), I would be far unhealthier than I am now.
Come on now, a couple Cokes a week is no big deal at all.
For example, I used to drink Coke or Mountain Dew at 14 meals per week. I've cut back to a hard limit of 3 meals per week (and 0 between meals), drinking either water or skim milk the other 18. It was a very good decision on my part.
Indeed. A couple cans of pop a week would not cause you any harm.
