20mg, but at 40 my speech was more “strained” than effortless. Dropping back down to 20 is definitely noticeably better. Felt like being back on caffeine (for me)… I definitely have a dopamine sensi...

That’s the thing with stuttering, it’s unpredictable on a day to day basis. There are words I’m usually fine with too, but some days I falter on them too. I find poor sleep (fatigue), caffeine and s...

A stutter can be caused by neurological disorders, TBI’s, and even autoimmune diseases. If not caused, in some cases, then at least those are a contributing factor. Me personally, I never stuttered un...

Yes I am a fast walker and musically talented, so I guess I don't have those mutations.  But I do lean towards the depression, daytime sleepiness, autism spectrum, and ADD areas....

I did 6 years in the Police and I feel you. The radio can be a nightmare at times. I know you posted about having ADHD as well before. When I got medicated, mine improved a lot....

That’s it. It’s really trial and error. Worth testing to see if it makes any improvement. Do you have any ADHD symptoms? Look it up and see if you present with similar symptoms. If so, then Risper...

No worries! I know for a fact if I have coffee or sweets, my stutter is much worse all day or even the next day. These substances cause a dopamine surge in the brain, which isn’t good for me. Take n...

Correct. And is not just dopamine. It’s a fine balance between all the neurotransmitters involved in the fine tuning of the speech motor neural networks. Dopamine is just one piece of the puzzle, bu...

There’s no test unfortunately. Typically, if your stutter is sensitive to dopamine swings, then substances like caffeine or sugar will exacerbate your stuttering, like it does for me. If you find ca...

True but I will add it is hard to do the detachment as you will. Stuttering is a string of thought but requires good mental energy to deflect those thoughts and actually detach. There are things you...

Yes, sugary + caffeinated coffee and energy drinks makes my stutter worse too! As soon as I stopped drinking these beverages, my fluency improved a lot. These drinks block adenosine in the brain and...

ok one question, if I drink energy my stutter gets worse, what does it say about my dopamine level....

Coffee makes mine worse too. I no longer drink it and I’m much more fluent. Caffeine blocks adenosine in the brain, which is what helps your body relax and eventually sleep. If you block it, it makes ...

I find anything that causes a sudden dopamine surge in my brain, makes my stutter worse. Coffee, sugary drinks/foods, smoking and alcohol. However, after a few drinks of alcohol (spirits), GABA take...

nicotine and caffeine make mine worse. Weed basically fixes it 100%. No anxiety = no stutter....

And when u don't drink your coffee the stutter gets worse...

Nicotine is a stimulant so it makes my stuttering worse, as does coffee. Obviously only if I exaggerate...

Are you asking if it effected my stutter? If so, there was no effect. It does help me focus a little better especially if I'm writing. ...

Research into the stuttering brain revealed a dysregulation in the dopaminergic system which affects the speech motor networks in the brain. Stutterers brains have either hyperactive dopamine baseline...

Ok, makes sense. It could be a contributing factor. For me, lack of “quality sleep” followed by morning caffeine and sugary drinks really impacted my fluency. Once I addressed those, I’m much more fl...
