Depends on what I have done.

If I am doing something *new* (which I have learned never to do, haha), and I can feel something bad right away and I STOP RIGHT AWAY, than 2 weeks minimum.

But, one time I did something new I thought I could do and I only did the thing for 2 hours, and it took literally 6 months for me to calm down.

I have been able to get some of them down to just a few days, but normally at least a week is normal. That is with huge self care / not doing anything in order to get things down. I am amazed at how much is required to get things to calm down. You almost really just need to not use your arms at all at that point.
