Bro I’m am from India have had severe stuttering throughout my life one thing helped me “Bhrami” it is a very inexpensive ayurvedic medicine (tonic) I also used ashvagandha (again an Ayurveda medicine/tonic) very inexpensive very effective both are good for brain & extremely effective for stuttering. If you want you can connect with me, just dm me. My stuttering is almost 95% gone. Unti I’m speaking in my native language. It comes back sometimes then I start bhrami again. I know it sounds stupid. Read about it first a ad if you want more info dm me. Ps: I’m not selling anything:)
