Unless I'm stressed, upset, tired, or haven't eaten much that day so my energy levels are low, I never find myself having any sort of an issue concentrating on a task, and taking in the full amount of information I need to. Wether it's studying, gaming, doing homework, etc. I've always felt I have a fairly sharp mind.

I've never known anyone who takes it, actually, though I've read many a story about ADHD people giving it to their friends. Seems Oxy, Vicodin, Percocet, Xanax, and other pain killers/anti-depressants just aren't enough for kids these days. I'll never understand when and how pills became the new weed. Guess it's harder to get caught. *shrug*
