I think the biggest change you can make it the amount of light in the room when you want to wake up. I changed rooms to one with much more light that comes in around 6-7 am and I have been waking up much earlier then I used to (and going to bed earlier). If you don't have any good windows that get a lot of light, you could set an alarm on some lights maybe.
I grew up living in a basement (jokes aside) but when I moved to an appartment with morning lighting i was finally able to get my sleep routing under control.
lately it has been suffering a bit due to minor depression and anxiety.. so I reduced my late night drinking and have started taking sleep aids about 11:30pm. This has helped a lot as well.
I think the biggest thing is just getting into a good routing, no matter WHAT TIME in the day that is.. just keep it regular.
