I stumbled on this comic from Extra Fabulous Comics today.
It really did feel like gaining a super power when I started my meds.
"My mind... everything... it's so quiet!"
That was my experience with being prescribed vyvance. I took adderall before and it helped a lot... but damn. Vyvance just did me so much more justice. It doesn't really wake me up if I'm tired, but I ain't trying to speed either. I just like being able to think (aka function)
