"gives the impression of improved brain performance without really delivering it"
Not too sure about that. I went off caffeine for six months once, then took a trip overseas (8 hours time difference) and had to drive 6 hours on arrival. At dusk, I noticed I was literally falling asleep at the wheel and drifting across lanes. So I pulled over to a coffee place, had my first coffee in six months, and it was like magic. No more drifting into opposing traffic.
