Once a month or so during college I'd devote a day to taking an ADD medication and working all day. I feel that I did more, and better, work under the influence.
I would start working on a Sunday morning at 8AM and besides a lunch break I wouldn't take stop until 10PM or so. I was working on an art major as well as doing some web development on the side at the time, and for these sessions I feel I was working at or above my normal creative and intellectual output for the majority of the time.
Besides a stamina boost for the day I also feel there is a similar effect to the Balmer Peak. (http://xkcd.com/323/) I would be much more confident then my average self, and because of it try (and sometimes accomplish) things that I would normally shrug off as out of my league.
