"I am a college student and found that for the first two months, Concerta worked wonders. It improved my mood, attention, and energy. It even helped with headaches. However, as I write this at 3 am, the side effect of sleep disruption has become unbearable. I either don't sleep for days or sleep for 20 hours a day for a week. Don't write it off, though. It is definitely effective and adjusting the dose may do the trick."
