In DnD 5e, there's no official rule for what happens when you are severely intoxicated. However, many DMs will houserule something along the lines of progressive levels of exhaustion, disadvantage on attacks, penalties to CHA checks, or the like.
Whether or not alcohol intoxication has a gameplay/mechanical effect or merely an RP-driving effect, are there any effects in the game that remove it?
Specifically:
- Are there any officially published (anything on WoTC website, including UA) rules, spells, or effects that directly and explicitly deal with removing intoxication in 5e?
- If not, are there any rules, spells, or affects that could be reasonably construed to affect intoxication?
Other helpful information: if there is an effect that explicitly mentions intoxication in a previous edition, that would be useful enough to post as an answer. For example, if there was a way to use the Medicine skill specifically to remove drunkenness in 3.5, that could be extended to 5e or adapted as a reasonable homebrew.

Since alcohol in large amounts acts like a poison - D&D 5e doesn't differentiate between poison and toxin, to my knowledge - you can use spells such as "Lesser Restoration" to get rid of its effects.
Also the following spell:
Both spells are level 2.
If your DM also gives you levels of exhaustion for drinking (which is a bit over the top, in my opinion) you can either sleep it off or use the "Greater Restoration" spell to remove one level of exhaustion.
Addition:
As @Icyfire mentioned, there are other ways of getting rid of poisoning, which includes alcohol poisoning.
Those are (no guarantee for completeness):
A quick search for "poison" in the Player's Handbook yielded the following additional results, which only provide benefits (unless you want to get drunk) to yourself, not to others:
Non-PHB features etc.
There might be other creatures in the MM that have similar effects to the Ki-Rin's lair effect, but I don't feel like skipping through any more poison damage attacks and monsters' poison resistances, Volo's Guide had enough of those.
