The problem is not that you're getting X hours of sleep and still feeling tired.

The problem is that you're not getting X hours of sleep on a consistent basis.

Try putting yourself on a solid sleep schedule, i.e. going to sleep everyday at midnight and setting the alarm for 8. It's probably not a big deal to slack a bit on the weekends, but the general idea is to go to sleep and wake up at around the same time every day.

In the beginning this might be hard, I would suggest that on your first night stay up until whenever you want until you're tired enough to sleep. Then, set your alarm for 8-10 or whatever and make sure you get up at that time. Later that night it should be easier to go to sleep at your target time and wake up etc..

Also, avoid things like TV and computers right before bed because they can make it harder to sleep/deteriorate sleep quality. If I may ask, when you're up late at night are you constantly watching TV or on the computer? I would be surprised if you weren't.
