No it isn't. Your lower esophageal sphincter is a little messed up, and is not very good for your health, either. Go to the doctors. Arrange surgery, if necessary. But as you aren't bulimic (hopefully), you should be okay.
No doesn't sound normal, get checked by a good GI doc.
sounds like gerd (gastro-esophogeal-reflux-disease)<br />
You NEED to see a DOCTOR!
A similar thing happens to me after eating certain foods, I'll spend the next hour or two burping the food back up...one time I came close to getting some on my laptop.
