Interesting. I was under the impression that Vyvanse was a more classic amphetamine than Adderall. Apparently I was wrong. One issue with Concerta is that the name brand and the main generic (there are two different generics) use a different release timing mechanism. I'm shocked that the FDA allows these to be marketed as the same drug. The generic results in a much more "wired" feeling, at least for me.
