I also have ADHD and as well I am taking conserta. I think if you push yourself too much in any kind of sport though it will be hard for you too breath. Just try to take it easy when you exercise. I wouldnt want you to hurt yourself. Do you ever feel really tired on Conserta? No doctor will give me a stright reponce. I hope you dont hurt your self. Just give it your best but remember to not push yourself.
