I became addicted to caffeine in graduate school. After many years, I finally quit entirely 5 months ago, simply because I no longer wanted to be addicted to it or schedule my activities around it. The key was to cut down my caffeine intake very slowly, over the course of many weeks, instead of trying to go cold turkey. It takes patience, but I never experienced withdrawal symptoms. I feel fine now and have no intention to go back. I do occasionally have a cup of green tea, maybe once a week at most, but there's no danger of my returning to my old habit.
