Thats a huge amount of soda to drink. I know its been said a lot now, but DAYUM that is not good for you. I drank ~12 oz a day for about a year a few years ago, but that really wasn't being kind to my teeth, so I cut it. I only drink it if I have to eat fast food somewhere now, and I'm sure I'm much better off for it. Water is good. -Juices can be just as bad (like, as in watching-your-weight-wise), a lot of them have high sugars too.
