vyvanse lasts alot longer and you wont have a come down the first few times you take it. if you do end up taking it more you are gunna need xanx to get you to fucking sleep. adderral will hit you faster and you can snort it(you cnt snort vy). I really dont think you should use them in the same day just because you wont need too. you have no tolerance the highest dose of vyvanse you can get is 70mg so yours is pretty high, same with the adderal bc you need alot less mgs for it to equal the same amount of vyvanse. anyways if you do the vyvanse first dont get impatient it starts to kick in after an hour. you will love the shit. so bottom line is save one and do it a different day

dont want your heart pumping to fast either.
