I can barely go one day with out a life water or bottled water.
Still not that good for you, and bottled water ruins the environment.
How is it possible to become addicted to soda?
Technically you can become addicted to anything if you make it your primary goal in life.Like drinking soda every chance you get.It's called indulging.
Not exactly. Certain foods/drinks have things in them that are physically addicting; as in causing actual side effects if you go too long without consuming it. Most things don't work that way though.
