i know exactly how you feel, i have that voice too, i keep telling it to bugger off and then i drown it with a bottle of water ha ha water is the key for me, i havent been feeling hungry cause my water intake has shot up but i am still getting the cravings at night, i just sip and sip and sip all night and count down till bed time, then its done i can go to sleep, and whilst sipping all that water i dont have time to nibble as i am up and down the stairs every 10 mins to the toilet (great excercise lol) try and drink as much water as you can, i have 3 litres a day
