I was a binge eater as a kid. I had this weird combo of restrictive anorexia and binge eating disorder where I ate 500 calories a day Sunday through Friday and binged on like 4000-5000 on a Saturday. I did actually lose 25lbs this way when I was 12. Was kinda cool 'cause I did it over the Summer so I left school chunky at 105lb and returned thin at 80lbs (I was 12 and only like 4'10 so that's not overly thin).
If you have to lose one of your senses? (I know there are now about 20 recognized senses but I'm talking about the traditional 5)
