I have done it several times!
This is how I cope, I have breaky later (9am) after having a few glasses of water or diet cordial.
Then morning tea I have something small, as I am not really hungry. Then push lunch back to 1pm or later and I have a soup (always) for lunch with a few celery sticks.
Arvo tea is usually about 3pm (I find I get really hungry in arvos) where I have some ham, celery (I love celery) with a teaspoon of philly cheese.
Then dinner is for 6pm.
I also have diet jelly, and diet yoghurt to eat when i need to.
