I agree with all of the above =- especially the pain relief bit. I hate taking anything but told them i wanted whatever i was due for whether i was in pain or not(and early on they were full on pain killers!) - and it really helped me get up and about without having to worry about too much pain.
Rest rest rest - enjoy the time you have just to sit and cuddle and enjoy your bubby! Drink lots of water, take vitamins etc
