Yes, do it. Ten years ago my husband and I stapled lead to the master bedroom walls and then drywall was applied on top. As I said to the drywallers it is safe as long as you don't eat it. No health problems ten years later, we are 70% finished our second home and will be putting in lead again. I am extremely noise sensitive, and the lead is a god send to help me sleep. I can really tell the difference when I try to sleep in one of the other bedrooms with no lead. Best $500 I've ever spent.
