Mine has changed a lot… it used to be only occasional but very severe blocks. Like in the Kings Speech but less often. Then I figured out how to not have severe blocks, but now weirdly I have repetitions and prolongations 🤷‍♀️ There’s no logic behind how our brains and bodies work. But, I’m not complaining, the stutter I have now doesn’t really bother me because I’m just so grateful I figured out how to not have severe blocks.
