In a preliminary study of people with restless legs syndrome (RLS), those taking the prescription drug pregabalin had fewer symptoms and spent more time in deep sleep than those given an inactive pill. The promising findings were presented at the American Academy of Neurology’s annual meeting. RLS affects up to one in 10 people. Pregabalin (brand name: Lyrica) is already FDA approved for treating nerve pain, seizures, and anxiety.
