Ramping off caffeine is actually quite simple. You go to the pharmacy and get 100mg or 50mg caffeine pills, and start taking 10% to 20% less caffeine per day than you were taking beforehand.

Do a little research beforehand, but the average cup of coffee has ~100mg caffeine. So 5x50mg caffeine pills for a week or two, and gradually decrease, and it becomes very easy to quit. I've done this successfully (and also chosen actively to get back on caffeine for performance/training reasons, which once lapsed, I then used the method again successfully).
