Adderall gives me energy for 3 or 4 hrs.
But the comedown is terrible. I don't have ADD.
I don't see the focus part. I have never taken more than 10 mg at a time.
I've read Dexedrine is smoother. And I think Vyvance too.
The only one I'm willing to try is the Modafinil (sp) but it's expensive.
I hope you can take other stimulant besides Adderall.
