Vyvanse is dextroamphetamine, while Adderall and Adzenys are mixed dextro- and Levo-.

While there are now generic versions of Vyvanse, they’re unlikely to be as effective until other developers work out the manufacturing kinks.

However, generic extended release dextroamphetamine is generally not in short supply and 10x cheaper than Vyvanse. Might be worth a shot if that’s what worked best for you.
