I have ADHD and stuttering is an everyday struggle for me now. I used to not stutter as a kid/early teen, but i guess i started stuttering around 14. Im 17 now and its gotten worse, but kind of changes throughout the weeks, it can be bad for a few weeks/month, and then for another few weeks I will barely stutter. Its so frustrating and confusing. I did notice that adderall EITHER helped my stutter, or made it worse. Never consistent though.
