Thanks to 8 am classes, I have a NEED to wake up when the alarm goes off. I was desparate enough last week to rearrange my room and put my alarm clock on the shelf that is opposite my bed so that when it goes off I need to actually get up to hit the snooze. I find that if I am up and walking to turn off the alarm, I have much more will power to keep walking to the shower as opposed to collapsing back into bed.
