I gave up caffeine for 2 years. Got tired of drinking just water, beer or milk. Sodas and coffee w/milk sugar are too tasty. All I did to quit was pop advil for a few days. Quitting caffeine wasn't remotely difficult physically. I used to drink 3-4 liters of soda a day, so not some small amount. I quit because I was worried about diabetes even though I was a healthy weight (as per my doctor's instructions).
