I don’t think we’ve done this before.
Anyway: first, some background. Pica is a mental disorder which is the desire (and usually compulsion) to eat non-food objects. These can range from the only mildly harmful–snow, paper, chalk, flour, mucus, etc.; to somewhat dangerous–blood, dirt, bark, ice, fabric, etc.; to things that can be toxic or otherwise deadly–glass, metal, oil, plastic, feces, etc… There’s a big long list on wikipedia.
There are two main causes of Pica: the most common is that the person has some sort of nutritional deficiency, and the body develops the compulsion to compensate. This is why there are a lot of pregnant women who get Pica–they’re trying to proved nutrients to the baby. If it’s not that, then it’s just a mental disorder, meaning who the hell knows. I fall in the latter category (I hope…no, I’m pretty sure I do). If it’s a nutritional deficiency, the treatment pattern is obvious. But if it’s not, they have to do a whole bunch of behavioral therapy in order to get the person to stop.
And it can be dangerous if the substance itself is dangerous enough, or if the person does it so compulsively that they don’t eat normally. Fortunately, I fall under neither of those categories. And so after much consultation with a doctor and psychologist, it was determined that the amount of paper (primarily) that I eat is not harmful enough to warrant behavioral therapy unless I asked for it. And I really don’t mind it.
So anyway: ask away!
