before alarm clocks

i found this little list interesting: seven ways people got up before alarm clocks. though i generally get up rather early (anywhere from 4:30 to 7), i hate having to get up for a particular reason. number one on the list, the water method, has worked for me in the past. between the water and the fear that i wouldn't wake up for that all-important event, i manage to be up in time. however, more often than not, the water and the anxiety make it so i never get to sleep at all.
