1. Figure out how much sleep you need (some people need 10 hours, some need 7- everyone is different)
2. Go to bed at the same time every night, and get up at the same time every morning. Routine is vital when you are trying to re-train your sleep patterns.
3. Don't do anything stimulating before bed (watch scary movies, exercise, read exciting books, ect.) and don't drink alcohol or caffine-loaded drinks within 3 hours of going to bed.
4. Have 2 alarm clocks- and I agree with putting them across the room.
5. Turn on bright lights as soon as you wake up in the morning, and have a morning routine that gets you moving right away.
6. Eat or drink something small as soon as possible to wake up your gut. Get in the habit of eating a good breakfast, and a light dinner.
7. Decide that this is what you really need to do, don't give yourself any excuses.
good luck! It isn't easy to train yourself to be a morning person, but is possible with the right attitude!
