Physical tips to reduce stuttering?

Physical tips to reduce stuttering? Does anyone have any actual advice that helps them stop stuttering when you feel like you’re about to stutter in that moment? I’m talking about physical stuff, like pinching you’re self or drinking or eating something specific, I know that you need to practice and change you’re mindset to actually reduce you’re stuttering overall, but I mean like stuff that you can do to become more fluent for just a second? Personally, if I bang my hand at my head quite hard, it goes away for a second, but it’s not very sneaky so it’s not very useful haha
