Well done for resisting its hard when u are hungry and cant get out to take your mind off it or work it off. Let hubby look after the kids for a while and go for a walk.
I have moments like this too but i stocked up on WW products so if i want a sneaky snack then i don't feel too bad. Just had some of their version of wotsits at 2 points a bag while waiting for tea to cook! 2 points isnt bad at all
You could maybe make yourself a small fruit salad or homemade soup with little points in it for when you have moments like this in future.
