This might sound kind of silly. But, I carry a tennis ball around with me. When I get serious cravings I find a nice hard surface to bounce it on, like a sidewalk or a brick/cinderblock wall. We have a basketball at work that I bounce around, too. Slamming something around that is meant to be knocked about might help with the tension. I have found that this kind of movement, testing my hand-eye coordination, helps me clear my head. Gives me a good reason to sneak away and be alone for a moment to unwind, cool off, and re-think the situation.
