Summer Schedule

So, I am awake and it is after midnight. This is how I truly know it is Summer. As far back in my marriage as I can remember Summer is the season of no sleeping. When we were on a mission trip in Croatia, I did not follow my usual Summer schedule. We are home now and the Summer schedule has taken over. I would really like to go to bed but my brain says, "stay up, you have no where to be." Staying up this late also happened when I was in college. Mind you, I am not a typical college student and not remotely close to a typical college student's age. I was hoping becoming an adult and having a career would mean "normal" hours and more sleep. I guess I misunderstood what it means to be an adult. My husband is however sleeping on the couch with not a worry in the world. I keep thinking about cleaning the house, cleaning up the yard, and other household things. I am also thinking about the next school year and what I can do to improve on last year. I do not wish to change myself but I wish that my brain could get off this weird Summer schedule. Is there anyone else out there that has a brain that likes to stay up late in the Summer? What to you do to "shut it down?"
