Well, there is no substitute for sheer determination, but I can share a few ideas.
One of the great things you learn while on Master-Cleanse is how much time you spend either preparing, eating, or thinking about food - and when all of the sudden you're not eating you find yourself with alot of free time on your hands. That combined with the increased energy you experience sent me off into a cleaning frenzy that lasted for all 10 days. My house never looked so good! the other thing I did was started collecting recipes (since I did miss some connection to food).
However, in your case I would say that its best for you to completely disconnect yourself from any situation where you would be near food during the dinner hour. If it means leaving your home and going for a workout, that would probably be the best thing to make yourself feel good, or get outside for a walk, clean out a closet, take a hot bath, take inventory of your kitchen and get rid of all the stuff that's bad for you, or anything really ... just as long as you're not dwelling on the idea that you're not supposed to be eating regular food. I don't know your living situation but if you're married with a family to feed, ask for their support for the next 10 days so you can have that time for yourself - it's only 10 days out of everyone's life.
Just remember that all the food you love will still be there once you've completed your fast. 10 days is not the end of the world, and its 10 days that you're focusing alot of positive energy on yourself, so take advantage of that.
