What other diets have you tried?

I was just wondering, what crazy diets have you tried? I've done Weight Watchers several times. I was a teenager the first time that I joined and I felt like I was starving. I would gorge when my parent's weren't looking! LOL! ( I did it before there even were points!) When I was a teenager I did Slim Fast. I also took those caffeine diet pills when I was 19. Nothing has taught me more than MFP though.
