I have the same thoughts. I know folks that are suffering from diabetes, and they drink soda every time I eat with them. And that boggles my mind. It's like they can't bear the taste (or lack thereof) of water. Or they are addicted to soda.
After moving to the U.S, I had more soda than ever before in my life, and that actually made me not like them anymore. Can't drink more than couple sips.
