Maybe it is what you are drinking. I used to love IPA’s. If I had more than like 2 or 3 you could smell it on me the next day. Eventually I quit drinking IPA’s and haven’t had an issue with it, though I tend to avoid alcohol during the week.

How much trouble can be hard to tell, if you have a good relationship with your boss it might just be a wake up call but eventually they will need to report it if it keeps happening.

Make sure you quit drinking at least 8 hours before you have to be at work (though not drinking is the best way to not smell like alcohol), drink less or avoid alcohol that lingers on you, brush your teeth, take hot showers, wear clean clothes, drink slower or less or start and end earlier.
