Can I ride in a car for 6 hours the day after Breast Augmentation?

I am having surgery at 11:30 tomorrow morning. Unexpectedly, my husband now needs picked up from work 3 hours away on Friday. Since I will be unable to drive, our 16 year old son has agreed to go get him. The location is on the outskirts of a large city and he is not familiar driving in that setting. I thought I would ride along to help him navigate through the metro. Would that even be doable? I will have a pain pump & could sleep for all but 20 min on way there & the whole way home.
