Alarm System

I need to create an alarm clock for heavy sleepers.  You know, one that has arms that can reach over and shake you until you are awake.  I have the misfortune of not only lacking sleep constantly because of my work hours, but the sleep I do get, I enjoy a little to much so I constantly over sleep.  I am suppose to wake up at 6:30am so I can get to my 8am class without rushing around and still get there on time.  However, my alarm never wakes me up.  I have tried just about everything to help.  Before the semester started I made myself wake up at 6 everyday for two weeks so that I could be use to waking up so early once school started.  This worked a little, minus the fact that I would go back to sleep.  Now that school is in session I started with two alarms...didn't work.  Okay, I'll try three, nope that didn't work either.  So then I heard that if you have a light turn on like a half hour before you wake up, it is suppose to be easier for you to wake up.  Well that didn't work either.  Today I set FIVE alarms, and opened my blinds to help me wake up.  I over slept by two hours!! I gotta get working on this invention, me becoming a morning person depends on it.
