I schedule appointments for early in the morning and make my son go with me. So he has to go to sleep earlier or deal with the fall out of being grumpy to me in the morning.
I give him a little leeway for the first couple of weeks of summer...in fact this is his last week of "freedom". Next week he will start volunteering at our Vet's office a couple days per week, and I will put him on more of a schedule with summer reading and music practice. Oh, and chores, lots and lots of chores. So, his schedule will even out.
I don't stay up until he goes to bed. When I am tired, I just say good night and toddle off to sleep. When I get up, I don't try to be quiet either. If he wants to sleep in he has to do so around my noise.
Since it summer, divvy up the chores more - have the kids take on more responsibilities around the house - feed the dogs, sweep, take out the trash, etc. Explain to them that just because they are out of school, that you are not, and you need the household to maintain a decent schedule to facilitate your school work. Just like you facilitate their school work.
When you get tired, just go to bed. Then makes lots of noise in the morning - vacuuming is a great chore to complete at 7am outside their bedroom doors.
Good Luck
God Bless
