Drinking?

My boyfriend and I want to celebrate our first year in college, by drinking. We have a 3 month old and his parents are here just in case. Baby normally sleeps through the night but you never know. Baby is ebf and sleeps from about 11-6 without eating.

If I drink after 11 will I still be okay to breastfeed at 6? I have formula so if I 100% cant I will supplement (or if he happens to wake up through the night)

But I obviously dont want to breastfeed with alcohol in my system.

I know the rule is wait 2 hours per drink.

If I cut myself off by 1 should I be okay? Should I cut myself off earlier?
