Interesting. Never noticed if that happens for me but I'll try and note it now. Being underslept, and certain medication like modafinil make mine way worse. Never noticed if alcohol makes a difference but I've seen others get way worse once they get drunk. Yeah I suppose every stutterer has their own set of consonants/vowels that are harder, and the start of your name usually ends up being one of them. Since I've read more into the background and science of it, and am aware it's purely psychological not physical, I've got more internal "tricks" to get around it - mostly the typical stuff like: switching out the first word/s of a sentence, breathing stuff, using "ummm", "I think", "well" etc at the start (not great practice but easy to use), I'm kinda lucky that speech therapy improved me to where I usually block before I stutter, so it gives me 'warning' and people don't notice as much. So now, when I block, I breath out the last word/syllable I was able to say, but don't engage vocal cords, so no one can hear me, but I tell my brain I'm still talking normally, then I can "flow" that breath/whisper into the next word. I know you didn't ask lol just started thinking about the techniques I've started doing since reading on it more, and wanted to write it down somewhere, hopefully someone might read it and it helps.
