Hypnic Jerks - 5 years

I have had hypnic jerks for 5 years now, since COVID. It seems like there's no treatment in sight. My psychiatrist thinks the Prozac triggered it, so now he's tapering me off of it. I take pramiprexole for the jerks, but I will still get them the first hour if the night or the medicine fades by 5am and the jerks start again.

What supplements worked for you? I've already tried meditation, breathing exercises, and the like. I feel like this is a deficiency I'm experiencing.
