Pain in the center of my body directly below ribs after drinking

Every time I drink too quickly or at all sometimes I will get an incredibly bad constant pain right below my ribs directly in the center of my body. It feels like a sharp constant pain that eventually goes away after 30 minutes and I can drink again the rest of the night without ever feeling it. I drink maybe once or twice every other weekend and if I do drink I will have maybe 5 or 7 beers, so I feel I am no way a chronic drinker.
