Hi. Nikolas. I have no news at all. I just read a post from Acanthaceae. He posted about something I've never heard about but from what I also suffer. I do this thing, rhythmic tapping. I've never heard it associated with stuttering. I've reached out to him, a true expert, also a stutterer. His research is very inclusive. Please check him out. Perhaps there is something in his most recent post that will tweak you. ❤️😺❤️
