happy music, write in my diary about the feelings, get some black tea, smell some coffee and as for foods – watermelon, cucumber, grapes – ideally water based fruits. I think eggs in the morning and a banana help a lot. i am sure the others will give you more non-food related ideas but here’s i try to handle my “tendencies”:-

I am a bit of sweet-food junkie and so i dont keep chocolates, chips or cold drink in the house, unless i need to. when i do buy that occasional chocolate or ice-cream, i make it a point to only buy one. If i get this craving for a cold drink, i make really really cold, slightly salty lemonade instead. I prefer to cook my meals instead of eating out and avoid eating while watching tv. a lot of over-eating happens because we dont pay attention while we are eating. its like filling up our mouths with something cuz those feelings wont go away. Its also a sort of escape from the present situation.

Mindfulness while eating makes a huge difference too.
