I didn't sleep well at night for months after my TKRs. Our solution was for me to move into the spare room, which I set up as my nest, with everything I needed, including a TV. Because I already had everything, I didn't need any help during the night. I even had my frozen gel packs in a cooler beside the bed.
That way, I didn't disturb my husband and I could watch mindless night-time TV, without stressing about not sleeping, or keeping anyone else awake. I often drifted off to sleep with the TV still going.
I caught up missed sleep with daytime naps and hubby got a full night's sleep, so he was fresh for work the next day.
