Yeah, it really does work! I only started mentioning I stutter during conversations in my early 30s, when my speech therapist recommended it. For some reason it never occurred to me that I could do this before, because I'd spent so many years hiding it. But yeah, lots of people misusing the word "stutter" here, maybe it's a regional thing. On the flipside, I've met a few covert stutterers who never mention they do, most of them being (I suspect) undiagnosed women.
