multiple jerks at rest

[[Za...]]

Does anyone else have jerks at night before falling asleep. I'm not talking about the kind that feel like you're falling and jolt you awake. But it feels like a sudden shock in a muscle group and makes you move suddenly. Mine are in my legs. I get them every 20 seconds sometimes for an hour. Is this BIND? It's been 27 months since I've taken a benzo.
