4 days post op.
I have slept in bed and on the couch. While there is a little pain with getting in and out of the bed, it's by far the most comfortable for me. I should add my bed is very low to the ground. So that helps a little bit, as I fall into bed, not climb into bed.
Although I have fallen asleep on the couch, the sleep is not near as fulfilling. I find I wake up constantly if I'm on the couch.
Are you wearing your stomach support? I have mine on constantly, it really helps with getting up/down.
