I found this in the bookstore

I'll just stick with my coffee. My main problem is staying awake in lecture anyways.

oh god coffee. I can't consume the stuff without running to the can ~20 minutes afterwards. And yes, ~20 minutes is an observed, measured, and calculated consistent amount of time. Iuno what happens but that's just what my body does.

Is it silly to use drugs in order to concentrate better and thus gain better grades?

Yes.
