Wanting to have a few drinks at the airport before my flight without my break smelling.

I am flying from Atlanta to Sacramento and was wondering if I could have a few drinks without my breath wreaking of it. I’m meeting my fiance in Sacramento and I would like to know if she would be able to tell if I’ve had a few to drink. I am bringing mouth wash and do plan to eat some greasy food after drinking as well. Let me know if I should just avoid it all together or if there’s any tips to get rid of the breath.
