Can I suggest the supplement L-Theanine? It’s the chemical in tea that is associated with preventing people from getting the jitters from caffeine the way they do with coffee.

I have ADHD and anxiety, so I’m always thinking of something. It actually manages to mellow my brain out to be like, “Yeah, that’s important…but is it productive to think about right now, this minute? Maybe not.”

I even started taking it with my morning dose of Adderall because it tempers the intensity of the side effects.
