There's a fine line, as with alcohol. A single cup of tea might feel refreshing. A monster energy drink is going to feel like a fight or flight response. Some people are also more sensitive than others and some are addicted more really than others.
I guess I am a little bias here too - if my caffeine intake goes near 200 mg for the day then I get shaky. I have a friend who can toe the line at 700-800 mg! Which I read the other day that is the 'danger zone'.
