well I recently gave up regular soda. I was becoming addicted to Pepsi. Seriously I had to have a can of pepsi with me almost constantly... and I used get grouchy if I went to long without one and I would get head-aches.... so about two months ago I was at the grocery store and I went to grab a 24 pack of Pepsi for the week (yeah, that bad!) and I for some reason backed up and said " NOT ANYMORE!" and got Diet Squirt instead and now I only drink that. plus I have cut myself back to two cans a day. I drink more milk and juice now. (plus I have lost like 10 pounds that I credit to giving up Pepsi)
