I don't know about you, but for me (what I do when I'm having a craving)...:
Brush my teeth - Um, well, sometimes it helps, but usually I do it after binge...
Shower - I take a shower twice a day anyway, so my mother would look me weird. But hot shower works for me, I get tired and I only want to have a tea and go to bed.
To-Do lists - my favorites. I like to plan everything. And at the end of the day I check the things I got done. Sometimes I do like "I wont eat before I've done this". Usually it ends that everything is done and I've binged (to "premium" myself).
Ten good reasons to be thin - I did it once. It helped once.
Make my own thinspiration book - yeah, I did that too. I should look it more often. This blog helps more.
Stepping on the scale before eating - This helps me. A lot. When I'm thinking like 'oh lets have a cookie' then I run into my room and weight myself, and when I see this stupid number 7 in front of my scale number then I don't even want that damned cookie.
Looking at people/thin girls around me - Sometimes it helps, sometimes it doesn't. Sometimes I get depressed ('I will never look like this...'), sometimes inspired ('I will look like this if I put down this chocolate').
Cigarettes - unhealthy, I know. But they took away my hunger.
