Random meds? It’s Adderall. I’ve been on it for years. I notice I stutter more at night once it’s worn off. Adderall has also greatly diminished my anxiety which my GP (not the doctor who prescribes my meds) says is common because when you have ADD you’re constantly trying to keep up and focus and then worrying because you can’t focus and you’re behind, etc etc so you get anxiety and sometimes depression. When I get anxious I stutter more so I’m not sure if it’s the Adderall that takes the anxiety away that means the stuttering is diminished or if it’s something else. I do know that stuttering and add occur in the same area of the brain so maybe we were “damaged” in that spot and that’s why we have both lol I have no clue.
