Seriously, all the time. It's always there. I've tried it all; drugs, therapy, meditation, breathing exercises, weird dental procedures, yadda yadda. The only thing that comes close to being a miracle cure (for me) are the AAF devices (Altered Auditory Feedback), but they're expensive as fuck, or if you're using an app or something, awkward to use in any practical application, and I don't have enough experience with them to say (only a trial period of an actual device), but I don't think becoming dependent on them is a good thing. But its effectiveness allude to some interesting stuff. >A brain scan study examined the planum temporale (PT), an anatomical feature in the auditory temporal brain region. Typically people have a larger PT on the left side of their brains, and smaller PT the right side (leftward asymmetry). A brain scan study found that stutterers' right PT is larger than their left PT (rightward asymmetry).[6] A second study found that stutterers with this abnormal rightward asymmetry had significantly improved fluency with DAF (Delayed Auditory Feedback), but stutterers with the normal leftward asymmetry didn't improve with DAF.[7] The study also found that stutterers with this abnormal rightward asymmetry stuttered more severely than stutterers with the normal leftward asymmetry. Exercise is the only thing that comes close to being effective for my "abnormal rightward asymmetry" type of stutter. If I shut down and stop trying to talk so much, it only gets worse.
