Rae, like the others I was up and about after 15hrs. I was in labour 4 days prior to that and I didn't feel that hindered me. I had little to no pain on resting and slight discomfort when moving but I agree with pain medication if it's offered. The nurses deal with it all the time and they can see when people need it - usually.
The one thing that was a concern was going to the toilet - maybe TMI. If you can tolerate them ask for prunes or prune juice to make it that bit asier and also make sure you are mobile and do your exercises they give you for strengthening and support.
Good luck.
