'Bulimia' Question... - How Do I stop bingeing and throwing up?!?

Talk to someone you really trust. Start eating healthy meals, so you won't feel like you binged. If you don't feel like you binged, you won't want to purge. If you feel the need to binge, drink some water or eat some fruit/veggies to hold you over until your next meal. About the tooth decay, you would have to ask a dentist.
