Restless Leg Syndrome

Anyone else have Restless Leg Syndrome? I have a severe case, it bothers me during the day and keeps me up every single night if I don't take Requip. It's a Class C drug so I'm not supposed to take it while pregnant. The idea of going without it scares me. I can't fall asleep and can't stay asleep and I'm afraid it's going to ruin my pregnancy. I want to be happy, not anxious and tired all the time. Any suggestions?
