"this is it. you might have to up or decrease you mg according to how you feel at first. i take 3, 18mg tabs in morning. it is the concerta er, lasts from 8-12 hrs. no side effects at all for me. i am calmer, more focused, and still get a lot done during the day. i easily go to sleep now. recommended for adhd though, not for add symptoms. i am energized during the day and do not &quot;feel&quot; like i am &quot;coming off something&quot;. i highly recommend this."
