Let's say I drank 50 beers. In a 20 hour period.... Lets do the BAC math from a chart on health.org.

10 beers @ 160 lbs. = .23 (.08 legal in MD)
Times that by 5 = 50 beers = 1.15
Now minus one drink an hour, which is = .02
Multipuly that by 20 = .40

thats a BAC of .75, which is still wayyyyyyyy over the limit.
