"i have taken adderall xr and vyvanse. they both have a similar but not completely similar feeling when it comes to getting work done. but mainly my experience with vyvance is quite good but not great. i take whenever i get up to go to school (6-6:30), and it takes an hour to kick in. i have been taking vyvance for the last 4 years. it helps you focus a lot more than usual and it gives you the motivation to get work done. but the downside about it is that you feel depressed for a minute or anxiety, but after a couple of minutes you feel back motivated and happy. also, i love that it gives you the mind clarity that i personally think everyone needs. overall, my experience with vyvance is awesome. btw i&#039;m 15"
