I go through bouts of sleeplessness, where I'll wake up 15 - 20+ times a night, it's extremely frustrating, especially when I have something important to do the next day, having something there to give me a boost on one of those nights, when it's obvious I'm going to struggle to get more than 4 hours of sleep would be brilliant.
I doubt it's designed to replace sleep entirely, but having it at hand for occasional use would make it an important drug for some people.
