My son is 10 and his biggest struggle with ADHD is emotional dysregulation (ED). We're going to be starting therapy in about a month, so we'll work on the behavior from that front, but I'm also curious if there's a medication that works well for this symptom. He's not currently on any medication. He tried ritalin and concerta, but we didn't notice any improvement in any symptoms, and had a few undesirable side effects, so we went off. At the time, he really didn't want any medication, so we didn't continue the search. (We homeschool, so we're mostly able to work around the focus stuff.)
So, what have you found helpful for ED?
