Hi Redann, extar pack should be fine. Have done that myself when the water hasnt shut up the hunger. Have you tried mix-a-mousse or making a muffin out of a pack?
Think the key is to fool your head. A muffin is solid, and therefore (well for me) I fooled my head into thinking it was actual FOOD.
Failing that - log off and go potter either around the house, outside for a walk, go for a drive - anything to take your mind off it xx
