if I do have a soda, it's typically a Diet Coke or Coke Zero... and I'm not a big fan of Coke in general... I just think it's the better Diet/Zero tasting soda out there that has caffeine. If you are trying to just do away with Soda entirely... Mio's are your friend... or there are other water flavorings that you can buy that have no sugar and make a big difference. And you can get these with caffeine added.
