Oh yes and is a problem even if they don’t have a bad experience with medication. All three of my boys have done that. My 15 year old son diagnosed ADHD and ODD has been on Adderall and Risperidone for years. The risperidone has helped with the hateful part. Then they didn’t want to take it. I made them a milkshake and put the medication in it. They didn’t even know.
