Late to the party but I've been taking 35-40mg of cbd per day for about 2months. I took cbd for sleep and it definitely works for that. But I have also noticed that my stuttering has significantly decreased since I began taking cbd. Hence why I'm even in this post. I googled to see if anyone has had similar results. My overall symptoms of anxiety have lowered by a lot so that my be the root cause of my reduced stuttering.
