Why do i feel like puking when i drink beer?

Your palate had become accustomed to it when you were drinking it more often. But since you've stopped drinking it regularly your body hasn't readjusted to it. Do you like the taste of beer? I would guess not since it seems to physically make you ill. Also do you haven any known food allergies? A few of my friends (two that have Celiacs disease, which is a wheat allergy, and one is allergic to one kind of hops sometimes used) physically get ill from drinking beer.
