One common method for quitting caffeine is to switch to decaffeinated coffee or tea. The process of decaffeinating these beverages still leaves a small amount of caffeine behind, although in much smaller quantities. If the person is only consuming one or two cups a day, drinking decaf can be a useful tool for changing this habit. However, in large quantities, the small amounts of caffeine in these beverages can add up over the course of a day.
