We didn't tell anyone our CS date. DS was born at 8.30am and we told no one til around 3pm (including family) it was nice to have the first few hours uninterrupted and free from phone calls, SMS's etc.
I keep on top of the pain meds and took everything they offered me regardless of whether I felt like I needed it or not. I think in day 2 I felt a sudden burning pain when I stood up but apart from that all was good.
Take all the meds they offer you - that's my advice!
