Nootropics

Sup intellinons, I'm writing a paper on the effects of Nootropic drugs and their uses as a "study drug" (improving focus and concentration among people undergoing intensive study), and I wonder if you might have any information about them.  I remember reading a topic on /r9k/ about one guy who tried it for himself and noticed a drastic improvement in his focus.  Anyone else have similar testimonials?

Also, does anyone know where I can find documentation relating to official trials in Nootropics?
