I tried a few meds for this. The most effective was Permax ( generic name was pergolide, I think. It is one of the L-dopa drugs used for parkinson's disease. I Have had both restless leg and periodic limb movement disorder ( PLMD-when restless leg happens in your sleep) I'm not sure about the connection between iron and PLMD but Restless Leg seems to be connected to low iron. I think some studies have been done. Maybe if your iron is low and you supplment it you can get off the valium just by taking an iron supplement. Good Luck to you too!
