i would and have stayed awake during op.
take full briefs so it doesn't rub on scar. before hospital make sure everything is easily at reach so no bending right down at home.
And lay flat in bed when you can even if you get that slight pulling sensation. With my first CS i didnt and i couldnt straighten out and walk for well over a week. by CS3 i learnt my lesson. And get up and walk withing 24 hours with assistance at hospital and take the drugs!!!!
