Mine has gone away too. I didn't so much stutter but blocked on words. I still do get it every now and again but it's not like it once was. I'm 37 now. When I was younger 13 - 23 i was afraid of calling or answering my phone. In my mind, I knew I would block on certain words which made it extremely difficult. I think confidence has a lot to do with it too. I mean I work in Casino Security Management which is mostly relied on communication. My radio channel is connected to 60+ people on busy nights and a minimum of 20+. I've done this line of work for the past 8 years. Interestingly though, I will still have days where I struggle on certain words and have to improvise or swap words around, etc but it's very manageable. I tend to forget about the blocks too which helps. The more you think about it the worse it is. I know this is easier said than done.
