Hello, I was diagnosed with ADHD in 2015 at 43 years old. Tried Concerta, Vyvanse, Adderall and Dexedrine. First two didn't work. Second two help, but only sporadically, and at high doses. I feel confident Desoxyn will be the best fit but unclear what to do. My current psychiatrist hadn't heard of it until I brought it up and now refuses to prescribe it.
