Yes! It is so annoying. For me. It happens in the legs. For a long time. It was my muscle seizing up and releasing. Now at least half the time I t’s a jerking motion. Keeps me awake at night. CBD used to help but I’ve discovered that I need to take a break from it because I build a tolerance to it. I think it’s made worse by interaction between all the meds I take. It is currently my least favorite member of my family of unpleasant symptoms.

Muscle relaxers help some. The jerking is anew symptom for me and it's the worst at night.

Yes
I’m trying CBD for this
It seems to get me to sleep so that’s a bonus
