side affects of concerta?? | ADHD Information

Hi! I am not completely an adult (well legally, yes), but I think that the side affects for adults are closer to me.  I have been on concerta 36mg(?) for 6 weeks and have completely enjoyed the focus brought on by it.  However, I have been shaky and sweating profusely under the arms since I started.  Is anyone else having this problem?  I tried metadate (didn't work) and a lower dose of concerta is not enough for the focus issues.  Does anyone have any suggestions?  Hope to hear from someone!!
