I saw that you posted that your son is taking Strattera and Concerta. I have an 8 year old currently taking Concerta 54 mg. It works well but the not sleeping side effect is a big issue for us. I get up at 6 am to give it to him and he still has great difficulty getting to sleep at night. He's usually up past 10:00 pm. we are going to give him a trial of the Strattera but I am wondering whether I can give him the Concerta too if it just isn't working. I am concerned with his days at school until the Strattera gets into his system. Please advise what you're doing.
