How does Concerta affect you?

My son was taking Adderallfor past 2 years, but today he started Concerta and I wanted to know if it had a cumulative effect on anyone who is taking it. From my observations Adderall did have that effect on my son and it took around a month for it to be out of his system. I was wondering how Concerta affects you or your child. I can find from people who are actually using the product or have children taking it.

My son recently switched from 20 mg. Adderall once and sometimes twice a day to 36 mg. Concerta once a day, over three months ago. He couldn't see any change. From my observations it seems like he's thinking more clearly. I know that Concerta lasts 10-12 hours but I am not sure about cumulative effect.

my son is 10 years old he has taken concera sents he was 5 years old .u can see a big difference in him from when he takes it and if he dosnt take it. he is much calmer and can focuse on what he needs to be doing .but it can make u loss weight .[/b]
