i can quit anytime

how do i classify my need for caffeine?  it is hard to say.  recently, i have had a conversation with a friend and we have discussed the meaning of addiction and what it means in relation to caffeine.

i am the first to admit that their are side effects to caffeine and that i feel them (including right now) when i do not have it.  but does that mean i have an addiction to it?  the problem that she and i both have with the term addiction is related to the "urge" or "compulsion".  check out the definitions yourself.

you see.  although i love coffee, as much as shoes, i can go a day without drinking it.  i can even go that entire day without giving it a passing thought.  today is a perfect example.  i am not "urged" to go and "get some".  i am not obsessed with having some form of caffeine in my system.  i'm not even compulsively looking for it. 

so then, what is this that i feel when i do not have enough caffeine in my system to feed my dependency on it?  i can clearly walk away from it and easily not have any.  yes, there will be some withdrawal, but the behavioral compulsion is not there... so what does this make me?  a social caffeinator?
