Am I at risk of getting addicted to coffee?

Okay, so I started drinking coffee few weeks ago, and during the first 2 weeks had either 1 or 2 cups a day, but have since started drinking it less, down to about 1 cup maybe every other day. I don't really feel a 'buzz' when I drink coffee, even with stronger coffees such as espressos. I was just wondering if there was any risk of me getting caffeine addiction..?
