I had a 37 hour labour before an emergency c-section, but afterwards I didn't feel *THAT* bad. I had morphine for 3 mornings, but then got sent home.
Laughing, sneezing, coughing and yawning were all undertaken with caution. I found it better to have my knees curled up to my chest if I did any of those as it didn't pull my tummy as much.
Turning over in bed was an exercise in control, too! I did turn over too quickly once, causing a lot of pain and shortly afterwards passed a huge clot.
That said, everything else was fine. I was picking up Erin from Day 1 in the hospital and putting her back in the bassinet by myself, so at home, there was no difference. I went out for walks after the first week but couldn't make it too far without needing to go back and feeling shattered for a couple of hours afterwards.
Basically, accept any help that's given - my mum & husband coked and defrosted frozen home-made meals respectively and that helped enormously.
When shopping, I found pushing a large trolley too much, so always went for a small trolley, with baby seat in it, so couldn't get too many groceries. Always accepted packing help and just took it easy packing it into and back out of the car.
