I agree - I grew up in Florida and my Mom did not let us drink soda. I don't remember her buying juice, but that might have been due to budget. I love water and drink it all the time. I do occasionally drink a diet coke, but if I'm thirsty water is the only thing that works.
On another note, there have been times that I have added crystal light or other flavored packets. When I do this for long stretches, it makes it harder to go back to plain water.
