Hey, I am not sure how useful this will be to other people but I figured I would contribute it anyway.
I have to say that I am new to this and am not sure if it is better or worse in the long run to use many of the coping mechanisms that I use, but I do have one more that is not up here yet.
Mimicking the noise being made, e.g. Also eating chips if they are or tapping on the table or even your leg where it can’t be heard, can make a significant difference sometimes. I hope this helps.
