Struggling with ADHD toddler

How do I wear out my 3.5 year old with ADHD? He never calms down. I let him run around like crazy all day, take him outside, we are constantly “doing” something but he never wears out. I am so exhausted by the end of the day I just want to sit on the couch. My other kids will play independently at this time, even my 1 year old, but my 3.5 year will not. He will jump all over the couch and me and throw things and scream and bounce off the walls until I force him into bed. No matter what I do I cannot wear him out.
