Anyone else feel a tremendous strain on your brain when you have to talk a lot?

Anyone else feel a tremendous strain on your brain when you have to talk a lot? It's extremely uncomfortable. It's not really a headache, but more like my brain gets exceptionally fatigued and just saying one phrase takes a lot of effort. And it lingers, for hours after I'm done talking, which normally already takes extra effort. But on days where I need to talk more It's sometimes a bit overwhelming and my brain feels like it's working overtime. I can't really explain this to people who don't stutter and It gets immensely frustrating at times. I think it's also due to the fact that when I'm stuck at a word I can't breathe, so a string of blocks makes one phrase not only take that much effort, but by the end of it I need to take a deep breath because It feels like I'm suffocating/asphyxiating.
