My partner has recently let me know that she needs to take a shot or a drink before going to social events that have 5+ people. I've never seen her drunk and she doesn't drink too much at the events themselves - but using alcohol to loosen up and feel less tense is enough to be an alarm bell for me. She does have a history with alcohol and an unusually high tolerance for it. She often drives after having one or two drinks, too. I feel safe with her overall but I have become really concerned about the way she uses alcohol to cope :/

here to vent, possibly get an advice on how to address this. part of me wants to just run cause I fear this might be something she wouldn't want to fix.
