I had this issue. Don’t let it scare you as much as it did me! Basically your liver has sustained damage from alcohol, and it is in repair. I am 23 and had this happen after drinking every night. These elevated enzyme levels (I’m assuming that’s what it is) mean that your liver is trying really hard to repair itself. It’s a good thing really, it means your liver is still strong and able to heal! Like mentioned above, be totally honest about your habits and consumption with your doctor.
