I hate when I start shaking, there's pretty much nothing I can do to stop it once it starts. The other night I was shaking really bad, I couldn't even fall asleep because I was just moving too much. I usually have to just wait it out, it eventually always goes away. I try to do something calming when I start shaking, or something time consuming where I just stop thinking about it because I'm so focused on what I'm doing. Maybe drink tea, that always helps me a bit, and do arts and crafts or exercise/stretch(that helps me a lot actually) or anything you like that you really have to focus on, it can be a good distraction
