Ugh. Blocks are the worst. For so many years I struggled on names, places, numbers, you name it. I find saying ugh or ums before a blocked word helped me get through them, but now I learned about making a soft sound and holding it into the blocked word softens the block. It works like magic when I do it right. Everyone here should read the book Stop Stuttering Short Course: How to Break the Stuttering Code. It offers these tools and techniques to reduce blocks and repetitions.
