subconscious binger

have you ever eaten a lot of something in a really short time and didn't realize it because you were busy working?

example: pack of yogurt, 15 minutes

i have this problem. i once finished an entire box of 12 granola bars in 20 minutes. i know the simple solution would be to not have a load of anything around me while i'm working, but it doesn't occur to me until it's too late. oh well. keeps me regular.
