Just an idea you might bounce off your doctor.
I use Trazodone 50 mg ... it is a mild sleep aid and anti-depressant. I have been using for about a week and get some help, albeit I have only rare RLS. I'm thinking in your case it should help you fall asleep,and "who knows" some anti-depressant may calm down the leg jerks.
Thanks, Jerry. I'll mention it to my doc and see what he thinks.
