Yorkiegirl, don't worry too much about the morning 'starving', IME at that time of the day it will easier to give her a drink at 6.30, then just whisk her along with distractionary activity. The break to routine will help, and don't try to explain it t her, that will only remind her that she can't eat!
Take things with you (well hidden) that she likes and are easy to eat, so that she can have something as soon as she feels like it when she comes round.
Good luck!
