I thought of this as it is all the small things which add up and might help someone else, however small.
adjusted the height of pillow under my head to relax my neck better,
lifted another pillow to cuddle to support my arm from dangling over my chest - side sleeper
cushion between my knees, to support them
eye mask about to go on (but I'm still faffing around on MN)
YouTube continuous sleep sounds, my favourite is washing machine spin cycle sleep sounds
Devices plugged in and charging
Fan on the far side his the room with a large bowl of iced water in front of it.
So what do you
