I know all the tricks. Put a different sound at the beginning of the word. Skip the sound you have difficulty with. Try saying it while exhaling. Stop trying to say it, and restart the word etc etc. I can assure you nothing worked. I am a stutterer. This is my reality. I'm trying to normalize my stutter nowadays to myself, rather than try and get rid of it. I feel the more I try to alienate it, try to get rid of it, the more it will stick. Maybe I'm wrong. Maybe I should try to rid of it. I don't know man.
