So I got a formal diagnosis (two, actually) and an Rx, and started taking it four days ago (at a lowish, introductory dose).
I'll quote:
"Holy Shit.  Holy Shit, @Tylae . Vyvance is the shit."
"Wait. I can just... remember things?"
"I'm not an unlovable piece of shit?"
"I can just... Do stuff without building a wall of awful?"
"It's NOT my fault my dad was an abusive drunk?"
"I don't have to use food to fill the void in my heart?"
"I can be around large groups of people sober?"
