Thanks, karma. I thought I was taking too little for that to happen. Apparently not. When I got a refill on the Vicodin, the RLS completely went away.

I found the same thing with the hot bath helping. Some nights I had to stay in the tub to fall asleep. Getting the water as hot as I could stand seemed to create a competing sensation. It would override the RLS feeling in my lower body.

Thanks for your corroborating input.
