Give her a big calendar she can "X" out the days until you leave for your next trip - a big smiley face on the actual day you leave works well. Good Luck.
Seriously, I'll be curious to hear any advice you get. I'm in the same boat. Although I will say, 5 days seems like a pretty long time to re-adjust. Are you talking body clock issues or re-inserting yourself into the family as a whole?
Depending on the age of your kids........One thing I find helps is to take over the family taxi service getting my kids to all their activities after school and evenings. When I'm gone, that is all on my wife and I think she appreciates getting that monkey off her back. Also, it gives me some time with the kids and her some alone time.
