Coffee has little to no affect on my energy levels, I just really, really like having it with breakfast. I either drink it black or with a little milk.
Same here. I just like the flavor. I like a cup of coffee after dinner with dessert. You take a bite out of your dessert then a sip of coffee, repeat.
It's a very cultivated thing to do.
I don't drink it in the morning though. The way I get my energy levels up in the morning is I just go out and start a fight with someone. Someone bigger than me, and lose. Then I'm feeling insecure the rest of the day and I'm at my sharpest and most alert when my self-esteem is at stake.
