Anecdata, but I've been on methylphenidate (Concerta) since age 7, and holy cow has it impacted my life in an insanely positive way. 21 years later, I'm still on Concerta, but excelling in my career, spending meaningful time with friends, family, and hobbies, and generally pretty happy with myself. When I tried dropping the meds in college, my life basically fell apart in a matter of months. My then-girlfriend now-wife almost broke up with me, I started failing classes, I lost contact with friends, and really struggled to feel alive. The Concerta doesn't fix my ADHD, but wow does it make it manageable. Thankfully, I had a supportive and invested family, understanding friends, and support structures all around me. I'm so glad my parents put me on meds instead of making me struggle throughout my childhood due to an outdated believe that "drugging kids bad". I owe my life and success to this drug, and while it doesn't work perfectly for everyone diagnosed with ADHD, it works so well for me that you'd have to pry my prescription from my cold, dead hands.
