Answers needed for background information

Answers needed for background information Hi Everyone! I wanted to write this post because I have seen many posts in this community! I’m currently dating someone who has a stutter and I would like to know if there are any other techniques he can use? He doesn’t stutter when speaking alone, singing or reading! I think thats so fascinating. I convinced him to try the McGuire Programme virtually and it has helped him. I tried the B1 vitamin and there wasn’t much change in his speech. He did have energy and lost some weight though. He is now taking L-theanine and it has helped alot to remain calm which I think is great. Any suggestions or recommendations are greatly appreciated! thank you.
