I know just what you're talking about. Before my sleep study and subsequent meds, I moved, wiggled, and rocked my legs when I was in bed. I could not keep them still any more than I could stop breathing. In fact, that's what it felt like if I tried to stop moving them - like I was holding my breath and I couldn't wait to take a great big breath. It drove me crazy, and you'd better believe it drove my DH crazier than that. During the day my legs didn't bother me but I rocked them, shook them, or moved them all day long.
My sleep study showed the doctor how many times an hour I moved my legs and based upon that he prescribed 1200 mg of Neurontin at bedtime. It has been a godsend. My DH and I both sleep like babies and I wake up in the morning with no after effects.
I have a friend, however, who has a more severe case than I and takes different meds than I. You're fortunate to have a good doc who's sending you in for a sleep study because that's the best way that I know of to get to the bottom of RLS. (BTW, I was allowed to take an Ambien before sleeping at the hospital so you might ask about that, in case you think you'll have trouble sleeping in a strange room with wires hooked up to you)
I agree that pain meds have done nothing to help with my RLS, but I'll bet the sleep doctor will be able to prescribe something that will give you relief. At least I hope so! What you have is miserable.
Hang in there!
