THis is what I do as well. I was never severe, but the sheer unpredictability of it was exhausting... maybe even more so if it had been worse and more constant. I think that there are three components to stuttering: 1. The neurogenic source, this the genetic part and I think it also determines much fo the severity and the ability to overcome a stutter. 2. The learned habit part. This is the anticipation part. I know that after a few weeks of more disfluency I start to expect it and maybe even precipitate it. I think I will stutter so I pause and then block and then have more disfluencies than if wasn't paying attention. I think this part is variable and perhaps what fluency shaping combats. 3. The last part is the psychological part, the part underneath the iceberg as it were. The shame and fear and self hatred and disgust even. I think a lot of people, even those who don't stutter suffer from. it the most difficult part to overcome. Its often a result of the stutter but getting rid of the stutter doesn't always get rid of the psychogenic part. I think you can have a semblance of fluency if you can get rid of 2, and 3 and all you are left with is the neurogenic part. And this is what I think you did. And why I am trying to do. I am generally very fluent and dont have to fight with the learned habit part. But when I am not I go through a season of disfluency I go down this horrible spiral of self doubt and shame. The stuttering persists as long as I am in the slump but as soon as I start to own it it and cope a bit, the stutter goes away. Its low key amazing. I just dont have control of that part of my psyche. Sorry for the we all of text.
