PASSWORD>aaI221mi7wL3IMy own child has been on Concerta since summer and is doing fine. Concerta is RITALIN plain and simple, it is just in a 12 hour timed release fashion. My child said that it helps to concentrate. We have noticed a tremendous improvement in academic abilities pre and post medication.I have taken it to see what it does too. I took 36 mg and was wired but 18mg I was fine. Perhaps these kids had too high a dosage. You didn’t mention the age of the children. The images may be from video games, some of them are pretty far out there. If they have been on ritalin before there shouldn’t be that kind of effect on them.
