Restless legs

Hi girls. I'm pretty sure I've posted about this before but didnt get what I was looking for. I am 27, almost 28 weeks pregnant with my second set of twins.. I am suffering really bad from restless legs. To the point that lots of night I just dont sleep. And with twin 2 year olds running around, I really need to sleep. On top of being physically exhausted given I'm carrying 2 again and my body is not handling it well, I'm also mentally exhausted. Trying to figure out what can help with this. I've tried compression socks, magnesium, exercises, baths. Nothing is helping. If anyone has had any luck using or doing something for this I'd love to hear about it.
