Hi Digby and welcome!
In answer to your question - yes, it can be done!
I didn't attempt it until probably about 6 months after my surgery. I felt comfortable driving during the day, but I was a little unsteady walking in the dark too, so I didn't want to risk driving, as since I didn't really have to, it wasn't an issue. When I did start at night, I made sure to remove all distractions (kids, radio..) and I stayed off of the highway. After a little practice on the quieter streets, I felt fine and even allowed the kids to get in the car!
You might want to try it out in a parking lot at night (with someone with you in case you can't drive home, of course). That should give you an idea of how it will be doing the real thing on the road.
Now I'm back to normal driving (which concerns my husband since I learned how to drive in NJ and NY -
), but hey, so far, so good!
Good luck!
Lori
