Has/Is anybody suffering from Restless Legs?

I have had this since 16 weeks pregnant, but now it's causing me insomnia. Which is not ideal as I have a 7 & 5 year old that are getting pretty fed up of tired/unmotivated mummy because of my lack of sleep. I can be so tired and excited to be getting into bed but within 10 minutes I'm wide awake because of this!

Does anyone have any helpful (non-medicated) tips on how to help this? I'm trying to do the recommended things online; walk to the bathroom/kitchen, gently massage, avoid caffeine (which is hard during the day because of the insomnia) I'm at the end of my tether now.

Thank you in advance for any advice/recommendation's xx
