I've never been on coffee. I only drink water since... forever.

It is true that getting coffee is kind of a social situation. But I'm ok just getting a hot chocolate or some other drink when I'm with people.

The thing about less ability to compensate lack of sleep. The way I deal with that isn't with sugar or caffeine. I just take naps. If I only got between 3-5 hours of sleep, I might need a 15-min nap but once I get that I'm good to go again.
