know exactly how you feel, iI used to try that all the time because i felt so guilty, but could never actually be sick. I guess so long as they dont carry on and do it too frequently it doesnt make them bulimic (if thats how you spell it?!) but they shouldnt feel guilty, diets dont work, full stop. Tried em so many times, but what does work if you drink loooads of water and eat only grapes for like 3 days, it completely clears your system and your brain, then after wards you feel like you dont really want to eat. Does this person feel like they need a diet?
