Wow, your post made me laugh and then sigh! No, normal sized people (even ones that want to lose 40 pounds) have no idea how desperate you can become. Or how each failure piles onto the last one until you've got your own Mt. Kilimanjaro to climb.
My mother (never had a weight problem, died of COPD) strongly encouraged me to take up smoking. Really! And, no, I didn't go there.
