Coincidentally, I'm about to go off to college, where I'm sure I'll be sorely tempted by "intelligence enhancers" like Modafinil. Even in my high school there is rampant abuse of Adderall and other stimulants. Thanks for the timely discussion of their effects - although I'm not predisposed towards taking them, I've now got some good information on why there's no need to do so.
When I'm well rested, well fed, healthy, etc, then the Modafinil just has the basic effect of increasing focus and energy while decreasing breadth of thinking, with the comedown 8 or so hours later that leaves me sucked dry. It's not that bad, but it's not so great as to be worth the risk on a regular basis, imho.
