I cured myself of that by getting a radio alarm and turning it up as loud as it would go; I basically shocked myself totally awake first thing. Nowadays just an ordinary alarm is enough because I have made it a habit to get up. (If you are not going to get up when the alarm goes off, don't set it - you will just be training yourself in the bad habit of ignoring it.)
Added: One of my responsibilities was to make sure my brothers got up in time for school. I can tell you from experience, that if you have someone to help, ice water is a great motivator to get out of bed.
