Can You Spell B-U-L-I-M-I-A?

Oh, God. I did it. Twice.
The following scenario sound familiar? Let's hope not.
Girl comes home from school, massively hungry from her insufficient empty-calorie lunch. She sits down with her dinner: leftovers. But, as she lifts her fork to her mouth something stops working. She eats and eats and eats untill she think she'll burst, then eats some more. Then she runs upstairs, and pukes it all out again.
Thats what I've done now, TWICE.
What's more, I'm the one here with a BMI of 30-effing-2. 32. I should be eating "small and regulated protions" not massive ammounts like some pig. Dammit!
