I'm embarrassed. I'm addicted to baking soda.

You know the little orange boxes? I can consume 2 of those boxes in a month.

If I don't eat it, my body just craves it. I cannot stop eating it. I can eat it with a spoon. If I run out, I panic. I now stock up on the boxes. I have 3 in my cupboard. Another thing I do, is I will eat some, swish it around my mouth (I like the grainy texture) and then spit it out. So I guess I dont always eat it and swallow it but I like how it feels in my mouth. I just can't give it up no matter how hard I try.

What's wrong with me?
