Will someone tell my Brain

It's been 3 1/2 weeks I was banded and I have lost 19 lbs. The biggest battle going on is in my brain. It seems to think I need food even if I don't. It's a continuous battle - asking myself if it's real hungry or my mind thinking it is. I guess this will be my battle for the rest of my life.
My friend Misty who was banded on March 17 went back to work yesterday. She is doing well having lost 26 lbs since her surgery. She worries about have time to eat a snack during our 10 minute break. i told her to figure it out before I get back.
