As far as your R & R goes, when I was getting ready to go, and on the plane, I felt incredible anxiety. It was unfounded.
It wasn't anywhere near as bad as I "imagined".
That plane ride will keep your mind wandering. My suggestion is to sleep deprive yourself, and try to sleep most of the way.
Also, before you leave, make a list of the things you want to do while you have your kids. That really helped me remain focused on the task at hand-being happy with my boys.
One last thing. DO NOT fall into any traps. Stay focused and be ready for anything from her-and I mean ANYTHING.
Best of luck, and my thoughts and prayers are with you.
