This was my experience as well. I had little in the way of actual withdrawal symptoms. My dependence was mostly psychological or cultural. Anecdotally, I think it's really interesting that people have radically different biological responses to caffeine. I have friends who drink much less than I did, but are hardcore dependent. I know people who get real headaches and jitters from tiny cups of coffee. I wonder if this heterogeneity is the case for many stimulants, or if there's something special and unusual about caffeine.
