It's fairly bitter on its own, but when you add sugar and cream or milk, it's really GOOD!
Even BETTER when you go to a place like Starbucks, where they use GOOD beans, unlike most "coffee shops" in the US, which use robusto beans, that aren't nearly as good as the arabica beans used in most of Europe.
I started drinking coffee at 17, while in high school, to help wake up in the mornings, but it became quite a habit, and then an addiction, during university, when I had to "pull all-nighters" studying for midterms and final exams. The addiction became even stronger while waiting tables, because I often had to close restaurants, then open them again, with only a couple of hours of sleep between shifts. When waiting tables, one is allowed only to drink tea, or coffee or water. Sodas are generally forbidden.
In the words of a really underrated comedy team from the 1980s...some late-night show...I don't remember their names...
