Wanttoheal said it better, because she was speaking from her own experience, but I'll second her.

What's on the front page of every newspaper today? Terri Schiavo -- whose bulimia caused her heart to stop! When you think about vomitting for weight control, think of that.

As Mortimer pointed out, emotional eating is learned behavior which can be replaced by more productive coping strategies. More important, though, would be getting therapy to address your self-image problems.

And trust me on this one: working those out will certainly do more for you than any amount of vomitting.
