Maybe. I don’t know. I think it depends on the person. I quit cigarettes cold turkey and have never touched another one since. My wife had to quit over months. We both smoked for the same amount of time and smoked about the same number a day.

Now I don’t feel I need to quit caffeine. I have a big mug of tea in the morning and that’s it. But I can see someone who drinks coffee constantly, and I’ve known people like that, having a much harder time quitting that than I did quitting smoking.
