Concerta (methylphenidate extended release - methylphenidate is ritalin) works pretty well for me....... i've been diagnosed with ADHD combined type since age 6. I was so hyperactive they threatened to kick me out of my preschool if my parents didn't put me on meds (according to my mother) and clearly they worked. been on ADHD medication ever since. I've had periods where i was off of them and my grades dropped severely. I am 22 in june... had to drop out of this semester because my antipsychotics quit on me and i couldn't handle school at all (stress wise) but i didn't need antipsychotics till i was 18. and before someone blames the psychosis on the concerta (again) i was still in that state when i was off ALL meds for a period in 2010-2011.... anyway, ritalin/concerta will help if you actually have a form of ADHD i got a range of As to Cs when i was on medication in college...
