One thing I've noticed as I've lost weight is I seem to be dropping my habit of tugging my shirt. You know, to keep it loosish so no one can tell I'm fat. Mind you, I'm still fat, but not nearly to the extent that I was. Don't worry about the mental adjustments: the good news is that you're losing slowly so you can make the mental adjustment slowly. I know of people who've done the stomach surgeries who just weren't mentally prepared for the change - then again, they weren't mentally prepared to lose the weight the hard way.
In other words, we're sane, they're not. Yay us, we win!
