100% this! I used to have a *very* severe stutter and could barely even talk. I did speech therapy will Bill Parry who founded this method and I swear to god it was like finding a hack for my stuttering. I still have issues of course, as it’s only been two months since I started, but now I have as many blocks in one full day that I used to have in one sentence. I haven’t stuttered for longer than a second or two in months. It used to take me up to 30 seconds to get a single word out. Stuttering itself (the condition) is not a choice, but the behaviors themselves are. Once you break free from those and know what to do instead of our old habit of struggling and forcing which was been reinstated into our brains for our entire life, it becomes very easy to break through a block.
