Have you tried supplementing with iron? I'm 40 weeks 3 days right now with #2 and my restless legs have been much worse this time until i started using iron. I was taking floravit but have switched to a new product called spatone which comes form the UK and seems to work better. I take 2 sachets a day in addition to 800 IU if vitamin E and a liquid cal/mag before bed.(Don't take the iron at the same time as cal/mag as they compete for binding sites) ALso, 2 cups of epsom salts in your bath can be soothing. And lastly, nettle tea is supposed to be very high in magnesium and could also help. Good luck!!
