I don't know why I enjoy chewing tissues, I don't swallow them just chew until they fall apart in my mouth then I spit into the toilet. None of my friends or family are aware that I do this. I also like the smell of sawdust but but wouldn't eat it. It's the texture and taste of tissue that I like. I've been doing it on and off since I was pregnant 16 years ago. It's a craving that's stuck, I guess. Does anyone else do it?
