Diet Coke

Is there any better drink in the world?  I mean...it has some flavor but it's not so sickenly sweet that you will get sick if you drink a ton of them, which I do.  It's not like Dr. Pepper that eats your taste buds up.  It's not totally lacking any taste like water.  It has zero calories.  I just don't think it can get any better than that.  I hear people say they drink too many Diet Cokes and then tell me they drink 6 a day.  I'm ashamed to even try to count how many I drink a day.  6 would be a good, low number day though.  I guess if that's the only bad thing I do, I'm okay, right?
