I'm sorry, I should have been more clear with my meaning. I used to think similarly to you regarding addition - I could quit caffeine any time I wanted for as long as I wanted, but ultimately, I went back to soda or coffee or what have you. So, I thought maybe that was the nature of addiction, that it was a subtle psychological thing. THEN, I quit smoking, and the hair-pulling, hand-wringing, eye-gouging experience that followed showed me what addiction was really like. On the other hand, my girlfriend quit smoking the same day I did, and when she quit it was like me quitting coffee; no big deal at all.
