I cheated in the early days and it made me feel worse, its just not worth it, keep up your fliuds, have hot drinks, rest, keep busy, sleep, walk - whatever it takes, but dont eat.
can you get a couple of days off work? that may help too.
after coming this far, it would be really unwise to eat, just hang in there.
i really suffered badly in first two weeks, but it has been worth it, it feels like an eternity when you are struggling, but it will soon fly by and you will have clothes falling off you!
