AdderaLL with the XL is pretty much the same as Vyvanse. I did better growing up with repeated dosages of an SR formula, but refused to take those post-methamphetamine usage which, with all of the side effects, seemed to turn me into some echo of the person I can be. And the pharmocological treatments feel too similar for my comfort, without the level of efficacy.
Vyvanse turns me into a zombie, and SR drugs make me feel like I am almost, but not quite, high. So I refuse both. I'm sure that Vyvanse would be the better choice, however, judging from the base reaction, excluding the feelings of a drug abuser. It is far more modulated. However, if you are comparing it to Adderall XR, I don't believe that there is a significant difference. Apparently, Vyvanse is not supposed to activate the pleasure centers of the brain, yet I did not experience any difference comparing mood, and functionality remained the same.
