I had ECS with DD, also for medical reasons, and it went really well. The most odd part was having the spinal block put in, being wheeled into the operating theatre and when they sprayed the cold spray on my tummy asking could I feel it (I could!), then 30 seconds later being asked again and by then I felt nothing. They wasted NO time in starting the operation.
I had 2 nights in hospital. The 1 thing I wish I had known was that you need to press your buzzer and not try to cope. Over the first 24 hours you might still be tied up wires, cathetars etc and it makes it difficult to get baby in and out of their cot.
Also, take in lots of drinks and snacks that can be left where you can reach them without having to go too far once your other half goes at the end of the day as it makes life easier.
It depends on how big our hospital is but I'd also suggest taking in ear plugs or an i-pod to block of the noise of everyone else coming and going.
Oh, and the other plus was that I looked far better in my post birth photos that friends who had been through a long labour. You get to wash your hair the night before and look semi ok once on recovery ward!
I took all of the drugs on offer and was glad I did. I was given drugs to take home for 2 weeks and by the time I had finished them I didn't need any other pain killers. The first few days at home you walk a bit funny but that soon gets better and after 2 weeks I was happy to walk the mile into town with DD in her buggy. By week 4 I was nearly back to normal speed.
Basically, do as you're told by the medial people, don't be overly ambitious and you'll be fine.
