Modafinil is a dopamine reuptake inhibitor though, it's just an atypical one. I can't take especially high therapeutic doses of either it or Vyvanse without getting similar physical anxiety.

I assume the reason it's not highly controlled in the US is that it's atypical enough to not be addictive (not that I've ever found Vyvanse to be addictive), but it is controlled in Japan and Russia and it's definitely possible to abuse it. People need their sleep even if it can keep it away for a day.
