My reasoning in giving it a try, is tthat it's meant to help anxiety. If a stammer is brought on, or made worse through anxiety, it may help. It may not mean I don't stammer, but stammer less, being less anxious. Around my wife and close friends, I'm not anxious and I'm more fluent (although, I still stammer). During presentations, public speaking etc, my anxiety kicks up and I'm less fluent. In my eyes, it's worth a shot. Also started taking 4000mg of lion's mane.
