Kneel before the toilet and put your finger down your throat.
Short-term solution: Drink something acidic (soda?). I found that the extra acid makes you digest food quicker, so in your case this is something that you have to do if you don't want to throw up :P (it worked for me plenty of times XD)
Long-term solution: Deal with it. Then, see a health adviser or a doctor (GP?) because dude, I like food, but I can control how much food I eat, so I'm actually quite slim DESPITE the fact that I usually eat until I'm completely full and that I love food XD. (oh I exercise too :P obviously >_>)
Point is, if you eat that much then you need to ask yourself "what am I doing wrong with my life and how am I going to fix this?"
:SEE! There IS someone on NG that is capable of proper constructive criticism >:D

I hope it doesn't go like the movie "Seven" and you eat so much your stomatch literally ruptures. Make sure no one ever finds out how much of a glutton you are, at least not John Doe. If you had eaten to the point where you would die, you probably would have stopped right when you started feeling bad. Of course, you could just be a glutton for punishment (literally) and you will in fact die. At least you went out happy.

Yeah, I'm cool now guys. I took a nap after I made this thread, woke up, took two separate massive shits, then went back to sleep.
Also, for everyone asking why I ate that much, I WAS HUNGRY.
