random intense stomach pain after drinking

Pple of reddit! I’m 29 😫 and have been drinking since college. I’ve really slowed it down, it’s mostly for concerts at this point. The past few times i’ve drank, I’ve stopped around 10/11 and then woke up around 1am with what felt like very intense stomach pain (just in the middle) followed by nausea, but I couldn’t throw up either time. It didn’t last long and I went to bed and was fine in the morning, but the pain itself feels so strong for a short time. Maybe heartburn? Has anyone experienced this? Both times I drank a few vodka cranberries so i’m not sure if the cranberry juice is contributing but will be paying attention to that next time I drink.
