Tapering off adderall and trying to find something that works

Brand new to this subreddit and came across it while researching tapering off adderall. Ive been on adderall for about 15 years, always took it as prescribed, but just getting tired of the cracked out feeling i sometimes get.

I did some research on this sub and it seems like these substances would help me to focus, but wanted to see if there is something i should add or take away.
