There are many more meds to try than just Vyvanse. If you have a good psychiatrist, they'll likely run you through Concerta, then Adderall, then Dexedrine, etc.
There are stimulants and non-stimulants. I personally took Concerta for a really long time, and it destroyed my personality and delayed my social learning by years. I then went cold turkey on it, and after 3 years, found that I was non-functional.
I've been on Adderall for about a year now, very few side effects (for me) and recently bumped my dosage from 10 to 15. Drugs affect different people differently, so you really just have to try them out.
