The Buddhists approach this a little bit differently, and it's not as easy as taking a pill, but I think it has it's own special benefits. And that's meditation. Not just any meditation, but Vipassana, which is simply being aware of sensations and equanimous with them, allowing all verbal thought to subside.
The mind races here and there, you have terrible (and wonderful) fantasies, you think about the future (personally, I love imagining giving lectures). The mind rebels, sometimes very strongly indeed and in all kinds of ways, against the act of simply observing the breath (or any other single object). Eventually, if you stick with it, something good may happen, and the experience will stick with you for a lifetime - and you can protect that experience with daily meditation.
