Coolgran I've had severe RLS for a few years, although not permanently. I'm afraid none of the home-grown remedies have worked for me. I've had my Ferritin Serum Iron tested and it seems to be normal, so there's something else going on. Diabetes is a risk factor, as are some other conditions. I took ropinirole for a while, but I wasn't convinced it was having much effect, so (with my GP's agreement) I stopped it.
When I have a bad attack, which can last for weeks, I've just learnt to accept it. It disrupts sleep. Thank goodness I don't work any more. If it happens at night, I get up and walk around and grab what sleep I can, whenever I can.
