I know you can't drive while you are still on pain pills (duh), but once you are off pain pills about how long after surgery should you refrain from driving? My son is going to a camp 3 hours away and I'm arranging for friends who sons are also going to drive him and pick him up because I know that is obviously not a good idea for me to drive. But how about things like 5 minute trips to the grocery store etc? Is is that you are still in pain and nauseous or are you also just out of it and not mentally paying attention enough to drive?
