Coolers and abdominal/chest pain

I drink irregularily, sometime 2-3 times a week, sometimes not for weeks at a time. Normally it’s beer, but lately I’ve gotten into coolers (Mike’s hard lemonade). Problem is I’m getting severe stomach/chest discomfort (honestly can’t tell which it is, my whole abdomen/chest feels like it’s on fire), to the point I have to take a break from whatever I’m doing because the pain is so bad. It happens after about 6-8 drinks. No difficulties breathing, no radiating pain (do not suspect heart problems, although I do have a somewhat benign heart condition, but symptoms don’t line up with my condition). With beer I have no issues. I’m going to stop with the coolers because it’s absolutely horrible going through this pain, just not worth it. But I am just curious if this is just a me thing or if it is common amongst people who drink coolers in higher amounts.
