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
