Wrist shakiness when drawing?

I’ve been drawing consistently for almost 2 years and recently I noticed that I get this type of exhaustion when I start drawing but it’s not painful, I usually draw with my arm, but I started noticing this kind of shakiness as if I drank caffeine when sketching/drawing. Which exhausts me and makes me not wanna sketch since the shakiness has gotten too much the past months. I don’t have wrist pain, but I’m just trying to understand what’s going on and if anybody else experiences this and what they do? I can always up the stabilization, but it doesn’t really combat anything Besides making a line more straight… yk how google is and when looking things up it gets kinda worrying :/
