This is my first Reddit post -- I read the rules before posting so hopefully this is okay. I'm not a person who stutters, but I'm an SLP who over the past 2 years has been very interested helping people who stutter. I hope it's okay for me to chime in even though I do not stutter myself. I just wanted to share a link to a podcast episode that may have some relevant information for you, but I am not sure if I am allowed to post a link here. You could search online for StutterTalk episode 200. Additionally, episodes 255 & 598 may have relevant information.
