Personally, I was on methylphenidate (generic for Concerta) from eighth grade until very recently, when I switched to an Adderal ER. The difference for me was more what happened when I came off of it- on methylphenidate, I got super irritable right around the same time I got home, which was not good.

I haven't noticed anything weird with this one, but for anyone reading this, I would highly recommend "shopping around" for ADHD medicine if you can.
