I stuttered as a kid and even now I stutter but very less maybe once or twice in a 20 min conversation. I talk like a normal person now, have a good job where I've given several presentations & talks, had a lovely girlfriend. The things that helped me were :- 1) I started taking slowly and breathing constantly. 2) Try to stretch the first letter of every word. 3) I don't do this but I've heard this has helped others - Try to picture the word that you are going to utter.
