Just thought I would share an idea that might keep your "significant other" from wanting to kick you out of bed every night due to the lovely RLS episodes that we all love so much. I'm in the U.S. and adjustable beds are becoming more popular where you can raise and lower your bed as needed for you and mine even has a setting called "zero gravity" that is nice for reading and watching TV.
Getting to the point, my wife and I bought one and we bought a "split king" which is essentially 2-twin XL mattresses that are pushed together so each of us can adjust our bed as needed. This is very nice for both of us but the added benefit here is that we are sleeping on 2 separate mattresses. When I am doing my "tossing and turning" with an RLS episode she is less disturbed on her side of the bed due to being on a different mattress. She wakes up refreshed and isn't telling me I need to go sleep in another room. I still feel like crap but at least one of us can function for the day.
"Cuddle time" is still available when appropriate but we both retreat to our own side of the bed for hopefully a long slumber for at least one of us.
