I began to drink coffee when I started attending university and, after a few months, I swore to never touch it again. I started depending on it and, at night, on days when I took two coffees, I could barely sleep. Of course, every person reacts differently. I'd suggest that you give it a go in a more relaxed moment of your life (vacations, for example). If it helps you, good. If it doesn't, quit it.
