For me, head hunger is "ooh, gotta have some....chocolate, potato chips, ice cream...a specific "gotta have it" or worse "gotta have MORE!" Whereas, real hunger is "hmm, I need to fuel up, I'm getting tired or light headed". This is a new sensation for me, I really don't know when I felt real hunger pre-surgery, other than if I'd been sick for a few days perhaps. What I try (and my brain is very resistant) is when it's head hunger I try to take a few minutes and close my eyes and ask myself "if you could have ANYTHING else in the world right now, what would it be?" and usually I find I'm bored, disappointed, overworked, anxious or something like that. SOMETIMES it gets me past the moment to know it's really emotional not physically driven. Also, head hunger is fueled by getting what it wants, and real hunger is satisfied by getting what it wants.
