you need to distract yourself in some way.
i have the muscle twitching too for two years now, it sucks and is terrible. i have noticed that since starting treatment, it is has reduced, and some days are better than others.
as hard as it is to deal with, find a way to distract yourself, you will notice it less. one way is focus on something you have control of like, your diet or light exercise if you are able to.
