Breaking the late bedtime is the difficult part. When I was a 9 to 5er, 11:30 was the typical bedtime, in fact, near midnight bedtime has been my life. When I switched to an earlier schedule, I could not break the habit. Getting the 2 hours in when I can gives me 7ish hours of sleep in a day. Wife is the same way, likes a late bedtime. I just don't see a way that I'm going to go to bed a couple of hours before my wife. I'd rather get that extra sleep before she gets home.
