I didn't drink coffee until halfway through college. I had to because the work was so ridiculously hard and time-consuming. We routinely pulled 'all-nighters,' going without sleep from 7 am one morning till 9 or 10 pm the next day.

By the end of my senior year I had only one goal for my life - to get enough sleep. That's about what I've achieved, I'm afraid.

I'm not surprised that Harvard is in favor of coffee. If they had to revise their curriculum and teaching methods to the point where students got a healthy amount of sleep, the university would probably fall to pieces.
