the same thing happened to me - i was never bulimic but it is the same thing in terms of digestion. With anorexia, there is nothing to digest in the 1st place so when you do eat your system is just out of whack. Bulimia, likewise, means that there is no food to digest either since it is thrown up before it can be digested. I just wish I had known how badly this stupid behavior can worsen IBS!
