when your tummy rumbles - try telling yourself that it is a good thing because it means you are losing weight. Thats one of the tips my hypnotist gave me
At least you will be burning calories whilst it is rumbling...
Mine is doing that today as its day 1 and hard at the moment. Others in the house just had steak and chips and I am starving. Tried glugging water but not helped yet. Think its all in my mind though.
