I wish I knew that some people never lose their hunger after surgery. No one ever mentioned this as a possibility and when I told people - and mentioned this on this forum! - people said, no, it's just head hunger. When I told the psychologist for my surgery center, she said that 20% of her patients never lose their hunger. It's very hard because you can't eat much at once, and it's not good to graze, because then you just "eat around" the surgery and don't lose weight. They ended up putting me back on metformin, which has helped a lot.
