I love coffee - black and nothing else on it! I always joke my wife that a man's coffee is pure black! My wife drinks coffee too but she prefers to have cream and her no calorie sugar in it.
I can't have a clear head after waking up without coffee, and I do drink more. Sometimes when I am at work, I crave for coffee too specially when I get tired and sleepy. I am just glad that the gas station in front of our office has a commercial grindmaster so they always have a hot coffee anytime of the day.
Actually, we do have coffee at work, but sometimes, I will just grab a cup from the store along with some other stuff that I want to munch on.
