Hi Sebastian,
I've also been off of Adderall for around 6 months and can relate to the lack of desire to do anything.
Quitting Adderall also made me realize that Adderall was the only thing keeping me at my old job that I couldn't stand. I decided to find a new job, and I hated every minute of the application/interview process. I felt so accomplished, though, after finding a better job. I realized I had no natural work ethic left after taking pills for 10 years, and finding a new job was a good first step in building that work ethic back up.
Now, at the new job, I am facing new challenges that are requiring me to continue building that work ethic, and it is getting better (it is still pretty bad, though).
For what its worth, I think building your natural character back up is a big part of the recovery process, and you should force yourself to do some of the things you really don't want to do. After you overcome your challenges, you will realize that you didn't need that pill after all to be successful, and it feels good.
