You're right. It isnt healthy. In fact, you can be hospitalized if it gets bad enough. You dont want to put that kind of strain on your heart. If you use diuretics, there is going to be a negative rebound, to some extent. The harder you push them, the worse the rebound is going to be. That being said, it doesn't have to be a 27 lb gain. Even for a 200 lb male, 27 lbs would be a good amount of rebound fluid. I can only imagine what that looked like on you haha! The key is reverse dieting. After the show, enjoy yourself that night and enjoy yourself the next day, but get things back under control before they get out of hand. Monday, go back to your diet and over time, add in more carbs, using the same sources you used in the diet. After a month, you should be in a better place. Through that period, have a couple cheat meals a wk. See what your body can tollerate. As long as you aren't going crazy and over doing the sodium, you'll find that you are more and more able to tollerate non-contest foods. Key is, take it slow!
