Well yeah, Ive kind of changed my sleeping routine about a month ago to going to sleep on a school night at about 9 pm - 10 pm then it takes me about 15 mins to fall alseep. Also I've been waking up at about 7am for school. The thing is even on a weekend when I go to sleep about 12 ish I wake up around 8am - 9am. not with an alarm, on a school morning I wake up with an alarm. Im 15, and there are no noises that wake me up because i keep waking up since a month ago between 1:30 am - 5:30 am sometimes twice like this morning I woke up at 1:30 then went back to slepe then woke up at 4 am and couldnt get back to sleep till 5:20am which really annoyed me. Any solutions? Also I go to the gym 3 times a week if that helps you.
