I've had a hard time getting up in the morning all my life, and it was worse in the winters after moving to Portland. I ended up getting an earlier version of this gadget (http://www.amazon.com/Philips-goLITE-BLU-Therapy-Device/dp/B...), and found that a few minutes of blue-frequency light every morning turned me into a natural early riser. (I still don't like mornings, but I naturally wake up and get out of bed at the same time every day)

Your circadian rhythm is especially susceptible to the blue end of the spectrum so instead of a 10,000 watt sun lamp you can just use one of these (or perhaps a home-brewed equivalent with the right LEDs) to let your body know that, if you were in a better lattitude, the sun would be shining right now.
