Guess what has come to my rescue?
Yup, my cellaphone, as the kids call it. We set the alarm function for 7:00 (get up!), 7:30 (start eating), and 8:00 (get in the car). So instead of me having to a.) remember that we are on a mission and b.) be the resident nag, the phone does both of these functions for me. We just obey the phone! Works for us.
