One of the reasons I was able to argue my ADHD was impacting my life negatively was the fact I was drinking enough coffee to hurt my health just to feel human and I still had executive dysfunction, so stimulants would be more effective and overall work as harm reduction. Now I'm not even on stimulants (technically), I'm finding bupropion works best for me. I still have a small cup of coffee in the morning, as it keeps me regular.
