A Naval Aviator lifestyle can be pretty good.  On the boat, expect 14 to 18 hour days.  Shipboard life is austere as well as requiring LOOOONG hours.  And obviously your totally away from your family.  Shiboard deployments last around 6 months.  Expect two to three deployments per tour of duty.

Ashore in a fighter squadron, expect more regular hours.  Normally, 8 to 9 hour days are normal.  When you're in carrier work ups (getting ready to deploy on a carrier) and getting all your quals, the workload and time away from family goes up, but it's still reasonable in my opinion. 

Both the above are during your sea tour.  Each tour lasts two to four years and you swap between sea tours and shore tours.

Shore tours vary tremendously.  If you go to a school, your hours are like any other student.  If you serve in the Pentagon or another big shore establishment like Chrystal City or Bupers, you'll have typical office hours.

My advice: the first thing you need to do RIGHT NOW is determine what it takes to get a commission.  I'm pretty sure an AS degree is not going to cut it.  You need at least a Bachelor degree and preferrably a BS.  You also need to enroll RIGHT NOW in an ROTC program so you can get commissioned as soon as you graduate.  ROTC can also help pay for your college tuition and books.  Getting a degree and then getting a commission through the OCS program is not the best way to go, especially for aspiring pilots.
