Joking aside i sleep on the left whats very annoying because i have to negotiate walking around the bed to get to the bathroom after i've had a drinking session down the pub?
BUT thats purely because Mr CRX has to be nearest the door of the room at all times for some strange reason. So when we are away i can end up on left of bed.
I sleep on whatever side of the bed is furthest from the door. This means I have an extra fraction of a second to react if an axe murderer walks through the door.
....Oh & I sleep next to the door - at least I can make a quick exit to the loo in the night without bashing me toe on the bed castor - very painful....
