3 or 4 different alarm clocks... one in another room. Have one beep, one play radio (talking... a program you find interesting like NPR), and ONE ALARM MUST PLAY BOB DYLAN!!! Bob Dylan is your back up. NO ONE can sleep through dylan. Having one on a radio station you find interesting is good because every once in a while you'll actually be motivated to wake up and listen. OK, good luck!
