Stomach Issues When I Drink

Over the past 2 weeks, every time I have an alcoholic beverage, I feel fine and don’t have any issues while I’m out with friends. The next day, whether it’s 1 drink or 5, I have this odd upper stomach pain that occurs. It’s not too intense but it is pretty uncomfortable and it does change my mood. I’ve always drank without any issues aside from the usual hangovers. I just turned 29 and I’m fairly healthy and fit. No underlying issues that I know of. Anyone else experience this or know what this means? At first I thought maybe it was what I was eating. Last night I had 1 seltzer as I watched a movie, woke up today with that pain. Laying down, food and water helps ease it.

Let me know if any of you have been through this. Thanks guys.
