Have fun with it!
I don't think we've changed anything around how fast people recover, only how much it takes to get drunk. It's possible that now that there is a lower cap to being drunk, that the effects take less time to bleed off.
Like if you think of it like a countdown... if it took you 50 drinks to get drunk and your drunkenness bleeds off at 1 drink per minute, and not it only takes you 10 drinks to get drunk, your drunkness would only last 10 minutes... that's the only explanation I can think of.
Also, I am making all these numbers up.
