>he wants nothing to do w help or therapy That's kind of the stopping point right there. I'm a huge advocate for speech therapy. It is my firm belief that most people can improve their fluency with therapy. I went from a severe stutterer to fluent for more than 25 years now. But... The speech therapy that worked for me in my mid 20s didn't help very much in my mid teens. The difference was me. I wasn't committed to doing the work. I didn't believe that I could get fluent. I didn't have the drive to practice daily. There are no approved medications for fluency. Nothing that has gone through trials has made it past Phase 2 trials. That's a dead end. Anything you might hear about is snake oil. Many 18yo men can be fiercely independent. If that's the case, I'd lay off. Maybe in a few years he'll consider speech therapy on his own.
