Hi hun. Im 4 days post op and was really struggling too. Last night I slep like an angel. I lay flat on my back with a large pillow behind my head, then put an extra pillow at each side so my face would roll on to it for comfort at either side. Doesnt sound comfy but I slept like a baby… might be something to do with lack of sleep for 3 nights tho lol. Dont worry too much about your legs being up hun, ive not put mine up at all whist asleep and doing fine xxxx
