Hi there Sugar,
Myoclonic Jerks can be controlled by meds in most people once they find the right drug & dosage. I get the occasional (maybe once a month) jerk on the meds I am on (Carbamazipine 800mg x2) but I put up with it because it completely controls my Grand-Mal seizures. A lot of it depends on how disabling you find them. Some people live with them because they are not much trouble.
