I was a strange case - I did it the day I came home from the hospital (2 days post-op). I was driving at 4 days post-op. I couldn't shower until the drain was out (1 week), nut I could do everything else. I was a little tired, but not bad. I've heard it's worse with others, though. I can hope you're like me, though. The key for me was getting off the pain meds - they really mess you up. But if you need them, by all means please take them.
I was one of the lucky few I guess. I was up and walking the morning after surgery with very little pain at all. Wasn't allowed to drive or shower until the drain came out, which was a week after surgery, other than some major bouts of fatigue lately it's been business as usual for me.
