I know this post is old but I was talking to mum the other day about my headaches when I was 10 or 11 years old and I was on 30mg of amitriptyline daily for just over a year - I don’t remember stuttering at all while I was on it. So weird! Hope life has been good to you. (I searched ‘stutter amitriptyline’ and found this post) ☺️
