I am in Tasmania Australia and started taking Sifrol. It actually worked for 6 weeks which was amazing, but now back to having attacks of Rls every night. Mine is severe ad painful, with arms, neck shoulders uncontrolled. So far I take 10mg Valium, but that is just keeping a li do things I think . Back to doc to try next thing. Ps - Sifrol will cause scary nightmares and alertness, but not sleepiness with me. But get sleepy during day. I've turned nocturnal and it's tiring. Don't want to live like this any more. Had enough.
