Thank you for your question and welcome to ADHDCentral.com.   I would not be able to provide information on whether or not your doctor has prescribed too much medication for your son. These concerns would best be discussed directly with your doctor.   As far as getting your son to bed, many children with ADHD have trouble sleeping (adults with ADHD as well). Using behavior modification techniques may help. In addition, make sure you follow the same routine each night to make sure your son knows exactly what to expect. You might want to begin the bedtime routine with a warm bath and then spend time with calming activities such as massage and reading a book together.   I am also providing you with some links to additional information that may be helpful:   Helping Children with ADD get to Sleep   Games to Motivate your Children   Creating a Discipline Process at Home   Behavior Modification        I hope this information helps.   Eileen
