I'm surprised you do this to yourself if your atheletic as most people with e.D's wish to lose weight and the best way to lose weight is to eat healthy adn excersise.
Its hard to stop but it is possible.
How do you feel before you throw up? Why? How do you feel afterwards?
The reason your throat burns is because your throat and stomach is being destroyed by the acids from your stomach, with the extremity of your case your gunna burn out your innards and wont be able to throw up, eat or breathe.
A bad sign is if you choke when throwing up, thats how must bullemics die. Choking as the throw up, or from the shock of having an acid reflux when throwing up.
When I stopped, it was gradual, I found if I was ta friends house, or had a friend over, under there watch I didn't do it. It's a mental thing and a behavioural thing to, its your attiude to it.
You
will have lsot weight if your throwing up and excersising.
You'll be feeling dizzy due to acid movements in your stomach from exercise and the fact that when you purge/don't eat healthy then you screw up the vits/nutrients your body needs.
Chances are the doc wont want you to stop doing dancing etc but may be worried it may become an addiction, thats not good.
You've gotta take control, its hard. Self control is what you need. You've gotta force yourself to not stick those fingers down your throat. Keep at it )trying to stop) and the first time you stop yourself from throwing up you will feel
excellent, from then on it gets better.
