Get out of bed immediately when you wake. Then drink a tall glass of cold water. Do not go back to bed.
I'm not a morning person, but if I've been up for more than an hour or two, eaten breakfast and gone for a walk before the events of the day start, I could probably fool you. The trick is to get up and get started.
I transition between morning and night, and it's basically getting into a consistent cycle. If you get out of bed at the same time every day for two weeks, you'll alter your cycle. The main idea is: don't go back to bed, get out of bed, take a shower, go for a run. DO NOT go back to bed.
