Hi D.,
Try to locate your local chapter of CHADD, which is a
national organization that supports families and those
dealing with ADHD. They can hopefully direct you to a
support group for your son. They also have meetings for
parents on a monthly basis.
Also, if you haven't already, speak to the doctor about
trying alternate medications. They are not all the same!
Both my sons are on ADHD meds, and it is a trial and error
process. Each person can respond differently. Some medications
do make kids more irritable, while others do not have the
same side effects. You may find a med that helps your son
perform in school without as much negative side effects.
Good luck!!
