I’m an Elvanse (Vyvanse for Americans) user, unfortunately. I don’t tolerate Methylphenidate well (they made me try like four different versions of it first before they’d give me the Elvanse) and as far as I know there is a shortage on just about all Dexamphetamine based medications.
Depending on how long it’s been since you’ve played, they’ve changed the rules probably like between two and five times since then, so you’d have to learn how to play pretty much from scratch anyway!
