Pramipexole
"I had suffered restless legs syndrome periodically for many years. Then, suddenly, I was getting RLS every night.  The weird thing, to me, is that I also had the feelings in my arms, but certainly not as frequently as the legs.  After weeks of trying to reposition my legs, ignoring it (impossible!), I finally went to my doctor.  I took my first dose that night, and haven't had symptoms ever since. I read up on the long-term usage, and am a little concerned about it. I'll cross that bridge if and when I cross it."
