a bed side commode is a great idea! no wandering around the bed or down the hall. just a quick dump of the bucket in the am. its also less tiring than the walk.

Bed side rails can help, or you can tie a rope under the mattress, and she can use it like a tug of war rope to pull herself up. Tie it to the bed post or bed rail if you like.

Learn to roll onto her side, then bring her legs over the edge, the push against the mattress with her hands to bring herself up. This way she isnt hoisting all of her weight, she is only pushing up her top half, as the legs should be over the edge. This is what they teach you after you have abdominal surgery so you can sit up without feeling like you are ripping your tummy open.

restricting fluids after 2pm can help, but in some folks we get the urge to go, and we must! even if its only dribbles. When an over active bladder triggers even on empty, it will demand that you get up. Perhaps she should be seen for over active bladder.

Sleep is so important. Having it disturbed night after night is no good for either of you. I hope you find a way to get rest.
