I’m in the spectrum and I responded to amphetamines atypically and I believe since starting on Addersll and Vyvansein my late-20s practically cured my life-long anxiety issues. It’s because my mind naturally wandered into anxious thought areas and got stuck there, trying to reason with myself (and you can’t use reason to stop thinking about death, one’s mortality, existentialism, etc) - whereas these stims allow me to choose what to think about, and I choose not to think about those things now. ...and the fact they’re also euphoriants helps too.
