My stutter is anxiety base. Talking on phone, talking to new people or meetings. Ashwagandha and supplements with l theanine have greatly impacted my life. I no longer feel anxious, waking up or go to sleep anxious. I have close to zero problems talking on phones or in meetings once it is not a long conversation. I still struggle but I now look forward to waking up and enjoying the simple things I have in my life instead of dreading my existence .
