Can you be addicted to coffee?

MsD💋
I drink coffee almost every day, mostly iced coffee and some days I have more than one cup. I'm trying to cut back but on the days I don't drink it I get moody and grumpy and I crave it so much so I just give in! Lol :( can you be addicted to it? I've heard people say you can be addicted to caffeine but I don't think it's true. Thoughts ladies??
