Can Vyvanse And Zenzedi Substitute Adderall For Adult ADD?

Hello, I have been diagnosed with adult ADD and went to my doctor. He has prescribed me both vyvanse and zenzedi. I was diagnosed a few years back and was prescribed Adderall. Of all three Adderall helped me feel like my old self again like back in middle school when I could focus. My current doctor will not prescribe Adderall due to it s habit forming tendencies it causes. Is there a way I can get it prescribed online?
