I know it is bad for my teeth among other things but...I read the title as I sit with a Coke Zero in my right hand. Guilty.
I will tell you that I went on a strict clean eating diet for 8 months. I ate almost no sugar and I was and still am crazy about brushing my teeth/flossing every night. It had been years since I had a cavity. I drank a lot of diet soda (I mean A LOT) and lost like 65 lbs in 6 months...however, I had a cavity that turned into a root canal after 8 months. I think it was from the acid in the diet soda.

But I still drink it. How foolish.
Have you ever tried coke zero and bacardi? Lol.
