I'm suffering from a problem where I urge to eat chalk, paint and cement. I'm having this problem from the past 2 years and in the beginning, I started with eating chalk than paint and nowadays I daily eat a little bit of cement by scraping it from the walls by my nails. I sometimes experience slight pain in my stomach and there is no such symptom of any special problem. I like the cement very much and cannot stop myself from begin eating it. While eating the cement. The brittleness and the sound produced while eating seems very relaxed and pleasant to me. Please suggest me, doctor, how to get rid of this problem or if it is normal for me?
