Remind yourself that this could be causing you some problems with health down the road. Drywall is NOT for eating. Just tell yourself it contains possible toxins, and if you continue this unsusal and potentially dangerous habit, you might want to talk to a professional medical person. You have no idea what they are putting in there, but some drywalls that are being imported from overseas are causing horrible mold problems for the housing industry.

I do agree, you should seek some specialist. I once met someone who liked to eat fabric. It was not for eating, but there was something about it that made that person love it, but it eventualy started causing problems. The specialist said that the best would be to fully stop doing it, but to make it easy, to swap it for something else that had resemblances. Have you ever tried it?

You have pica, a persistent craving to eat nonfood items. I have known people who eat cornstarch and ice. It occurs in children most often but pregnant women sometimes experience such cravings also. People with pica frequently crave and consume nonfood items such as:

•dirt
•clay
•paint chips
•plaster
•chalk
•cornstarch
•laundry starch
•baking soda
•coffee grounds
•cigarette ashes
•burnt match heads
•cigarette butts
•feces
•ice
•glue
•hair
•buttons
•paper
•sand
•toothpaste
•soap
It is believed that a vitamin or mineral deficiency leads to pica. Since you are a female, the culprit could be an iron deficiency. You should get bloodwork done and take an iron supplement if this is the problem. Please let your parents know that this is not simply a bad behavior but a physical compulsion, much like craving a certain food.
