Is food a habit or a hunger thing?

I think it's a habit. My roommates left cookies on the kitchen table and i noticed that I was eating them. That was weird. I stopped the second I noticed, that's another good thing about the hypnosis is that I'm more mindful.  If I think about it, I notice that I'm not always hungry when I'm eating, sometimes I just need to fill time or space or I'm thinking about something that I don't want to, so I start to chow. Oh well. It's good to notice so I can stop before too much damage is done.
