Sunshine or bright lights
The first thing you should do when you wake up in the morning is to expose yourself to at least fifteen minutes of sunshine or bright lights. Preferably with your eyes open.
Exposing yourself to bright lights helps to set your internal clock, which by some quirk of nature runs on a 25-hour cycle.
It is important that you need to reset this internal clock every day so your body knows that it's time to wake up and in the evening your body knows it's time to go to sleep.
If you have blinds or curtains on your window and you can reach them from your bed just reach over and open them.
If you can't get natural sunshine into your room when you wake up then turn on the lights.
Get an extra lamp or special fluorescent tubes if you have to, but make the room bright.
You can buy special fluorescent tubes at aquarium stores or plant nurseries. You will need bulbs with 600 lux or more intensity.
