I don't know. I can feel a slight dependence on caffeine if I have been drinking a lot during some weeks and then stopping cold turkey (slight headache, possibly slightly more tired in a day or two) but it does not feel very addictive.
For a long period of time I only drank coffee during the week and not weekends, sometimes I stopped some summers and when I slept badly I stopped drinking coffee for a while. No problem at all with any of that.
I do like like the small energy burst in the morning when I'm working and I like the ritual when it is winter in Sweden it is dark and cold outside and you are freezing, then drinking a cup of coffee as you start up your computer is nice.
