How Do You Get Back on the School Schedule?

We are two weeks into school starting and I don't know about you, but I'm exhausted!

All the after school practices, meetings, homework and paperwork are making it difficult for me to get to bed at a decent time. I'm hoping things will settle down and we can get into a schedule. Otherwise ... I don't know how long I can do this before I "hit the wall."

How do you get back on the school schedule? Do you have any tricks?
