Is it pure hydrocodone, or mixed with APAP?
The Tylenol/acetaminophen/paracetemol/APAP/acetylamide phenol is bad as-is for your liver, and worse if you drink heavily. That's bad even when you aren't currently drunk; it's bad if you drink often enough for your liver to be inflamed/damaged/reduced in capacity.
For purely hydrocodone products, the danger is mixing two downers. For that, you want to have come down from the booze enough. Can't tell you when that'll be, because it depends on how high you got, which depends on how fast you drank those beers. Really, if you're halfway down but firmly on the downslope of hooch, you're probably going to be OK.
Overnight passed out, you'd be ok in the morning.
