I love a good diet pepsi...has to be fountain with lots of ice! I also drink iced tea. During the school year, I have a glass of ice water on my desk all day long and have either a dt pepsi or iced tea after school on my way home. I try to stay away from anything with caffiene after about 6 pm or I find I can't fall asleep at night. When I am sick...I need the fizz of the dt pepsi so I drink it all day long.
