I started driving after about 5 days. My surgery was on my right hip, so I had to break with my left foot. It was a little awkward, and I did not drive any long distances the first few weeks. Mainly to the grocery store, etc. but it felt really good the first time I drove myself again! I have a desk job and took 4 1/2 weeks off work. I was hoping that they would put me on half-days the first few weeks, but they did not. I think I made a mistake by walking into our medical department without any crutches or cane. When I have my other hip done, I will make sure I walk in with the cane, and a lot of extra hobbling, to see if that works better!
As far as the pre-op jitters, I had them too, and my experience was very similar to Sean's (of course, we do have the same doctor). The IV was the most painful, and even that was not as bad as I expected, because they gave me a small shot to numb that area before they inserted the IV. I don't even remember being asked to sit up or turn for the spinal. I was out as soon as I got up on the operating table, and next thing I knew, the surgery was over and I was wide awake and feeling great! Probably a little high on some of those painkillers!
