Personally, I've had all of my difficulties with getting up early solved by the quick caffeine trick. In short: have an alarm clock sound an hour or so before you should actually get up, when you reset it spend 10 seconds grabbing a caffeine pill and swallowing it, set the clock to repeat the alarm in an 30-60 minutes, and go back to sleep. By the time your clock will sound again, it's likely that the caffeine will have made you want to get up.
