I am writing in hopes that your answer to this question will help other readers. A few years ago, when I was in college, I discovered that my college roommate was bulimic. My boyfriend and I found evidence in the mornings that she had been vomiting on a daily basis; she also developed weird eating habits (at 6 A.M., she would wake up and buy two pints of ice cream and eat it all, and then not eat for the rest of the day). We didn't know how to address the problem, and were afraid of hurting her. When we called the Health Service, they took the "my best friend is bulimic" line to suggest that I was bulimic instead! I didn't want to become the food "hall monitor" — are you eating? What did you eat today? etc. — but we tried to include her in healthy meals.

Eventually, some other stress factors in her life calmed down and her binge/purge behavior seemed to subside. However, I've always regretted that I couldn't attack this situation head-on. Do you have any advice for people that might be in a similar situation?

A friend of mine takes laxatives to keep her weight under control. The directions on the box say that you should only take two a day for no more than a week. She has been taking two to six a day for two months now. I was wondering what possible physical side effects might result from this kind of activity.

I have been chewing and spitting large amounts of food (pretty much always sweet stuff — pastries, chocolate, etc.) almost every night for eight or nine months. I am eating a healthy, balanced diet otherwise, maybe a little on the lower caloric side (1300 to 1500 calories per day). My chewing and spitting sessions usually follow a balanced meal. I know this is a type of eating disorder. I have done a lot of research online and I know that there are side effects, although they vary depending on who you ask. Some sites mention that chewing and spitting activates the release of insulin and results in hyperinsulinemia, insulin resistance and weight gain. Is this true? How long would it take to develop these problems? Are these reversible if I were to stop this behavior?
