You also need to ride in the back seat for 4 weeks - that whole airbag thing is an issue. Understand that if you start driving at 4 weeks (I think many folks here were told not to drive until 6 weeks out) you do NOT want your children to ride with you until you decide if you are capable of driving. Your concentration will be faulty; I drove at 4 weeks and would not have tried to go out of town or on a high-speed road - I toodled to Cardiac Rehab and the grocery store and that was hard enough for a couple weeks. The distraction of having kids in the car would have been problematic for me; so play it very conservatively.
Try to write all your bills before surgery and have someone reliable mail them for you on dates you put on the envelopes. Post-ohs is NOT a good time to use a checkbook. I have personal experience with this - a BAD personal experience (thank God for overdraft protection).
You'll be quite amazed at the concentration and memory deficits you'll experience - you might want to sit down with your kids and let them know that you'll need their help remembering to do things for a few weeks. This is normal, and it may scare them if you don't give them a heads-up.
You need to have updated wills, living will/durable power of attorney.
Let your friends know that you won't be "entertaining" for a few weeks. I found that a couple of friends for an hour wore me out for the day. Chatting and noise are hard on you.
Recovery from this surgery is unlike any other; although it's not particularly painful (except if you lift something too heavy, or stretch too far, or have a dog pull on a leash, or have something hit you in your incision, or heaven forfend, sneeze), it's very debilitating. You'll be tired more often than not, and still have trouble sleeping. You'll have trouble following a conversation, or TV show, or book. You'll need to participate in your recovery by walking and using your spirometer. You may become depressed - very common. But it's all an investment in your future and things will get better, in fits and starts.
Treat yourself and your family during this last week before surgery - good food, good drink, a day spa, movies, shopping. It'll be a while before you'll be able to enjoy such things.
